CHANGELOG.md

Changelog

All notable changes to lucidVIEW are documented here. Format loosely based on Keep a Changelog, versions follow SemVer.

v2.6.0 — 2026-04-12

Added

• HTTP-aware image cache with proper LRU and per-image metadata sidecars. ImageCacheService now persists ETag / Last-Modified / Cache-Control: max-age / Expires / fetch and access timestamps to {hash}.meta.json files alongside each cached image. Reopening a document within the freshness window skips the network entirely; stale entries send conditional If-None-Match / If-Modified-Since GETs and use 304 responses to refresh metadata without re-downloading the body. Disk eviction now also unlinks the sidecar. In-memory cache uses a LinkedList<ImageCacheEntry> + Dictionary LRU with O(1) access and bounded capacity (256 entries by default). Verified end-to-end against shields.io: first load = 200 + sidecar write; second load = STALE → conditional FETCH → 304 → cache hit (no body re-downloaded).
• ux-scripts/verify-{ruler-visible,render-mermaid,export-pdf}.yaml — three new harness scripts that exercise the bug-fixed code paths end-to-end.

Changed

• "Render Diagram..." → "Export Diagram..." in the side panel. The menu was a misnomer — it opens a save file picker, not a render preview dialog. The handler is now async void so any exception surfaces on the UI thread instead of disappearing into a fire-and-forget Task. The status bar now shows Opening export dialog (N diagram)… immediately on click so the user gets confirmation that the click registered, even if the native picker takes a moment to render or appears as a sheet on a different screen. Cancel feedback shows Diagram export canceled.

Fixed

• Ruler regression: a previously-saved contentMaxWidth larger than the current window width stranded the right ruler handle off-screen. ApplyContentMaxWidth now clamps to EffectiveMaxContentWidth = min(2000, Width − 60) and recovers automatically on launch (resetting to 900 if the saved value is out of range). The clamp is also applied on every drag/click and re-applied on SizeChanged so shrinking the window pulls the right handle back into view.

Mostlylucid.ImageSharp.Svg v0.2.0

The bundled SVG renderer + svg2png CLI both jumped to v0.2.0 with significant feature and performance gains:

Features added

• fill-opacity / stroke-opacity are now inheritable through the cascade and applied separately from element opacity. This was the missing piece for the shields.io drop-shadow text trick (fill="#010101" fill-opacity=".3").
• Real LinearGradientBrush / RadialGradientBrush with full gradientUnits=objectBoundingBox|userSpaceOnUse, x1/y1/x2/y2 or cx/cy/r in % or units, and href stop-inheritance chains.
• <marker> support (arrowheads) — every SVG path command (M, L, H, V, C, S, Q, T, A, Z) is parsed by a hand-rolled tangent extractor (SvgPathEndpoints) so marker-start / marker-end rotate to match the path direction. Mermaid edge arrows now render correctly.
• clip-path="url(#id)" via ClipPathExtensions.Clip — supports rect/circle/ellipse/polygon/polyline/path inside <clipPath>. Shields' rounded corners no longer rely on the rect's own rx/ry.
• rgb() / rgba() / hsl() / hsla() color parsers added to SvgValueParser.ParseColor. Mermaid pie slice fills, flowchart edge label backgrounds, and any SVG with non-hex colors now render correctly.
• Embedded DejaVu Sans font (739 KB) shipped inside the library. SvgRenderOptions.ForceBundledFont = true (default) ensures byte-identical text rendering across Windows / macOS / Linux instead of falling back to whatever the host has installed.
• SvgRenderOptions.Configuration — pass a custom ImageSharp Configuration (e.g. PNG-only) to let the AOT trimmer drop unused encoder modules.

Performance

Bench	Before	After	Δ
Shield (~1 KB SVG)	911 µs / 1627 KB	820 µs / 1211 KB	−10% time, −26% alloc
Mermaid flowchart	13525 µs / 2651 KB	13352 µs / 2172 KB	−18% alloc
C4 container	36111 µs / 6113 KB	34999 µs / 4475 KB	−27% alloc
Render-only (shield)	342 µs / 1208 KB	276 µs / 855 KB	−19% time, −29% alloc

Hot-path optimizations:

• InheritedStyle.Merge — fast path that skips dict creation entirely when the element has no style="" and no class="".
• SvgValueParser.ParseStyle / ParseNumberList — return shared empty singletons when input is null/empty.
• FillAndStroke — solid-paint fast path collapses to ctx.Fill(Color, IPath) instead of allocating a SolidBrush.
• DrawText — converts text to glyph paths via TextBuilder.GenerateGlyphs and fills them as regular shapes, bypassing ImageSharp's heavy text-rendering pipeline. This was the single biggest win — ctx.DrawText was allocating ~250 KB per call internally; the path route shares the existing fill machinery and is dramatically lighter.
• MeasureSize skipped when text-anchor is start (default).

Tooling

• Mostlylucid.ImageSharp.Svg.Benchmarks — BenchmarkDotNet harness with 3-tier benchmarks (shield / mermaid / C4) plus an alloc mode for per-stage allocation breakdowns.
• Mostlylucid.ImageSharp.Svg.Conformance — resvg-comparison harness with multi-metric reporting (MSE, % pixels close, % exact, max channel diff). Forces both renderers to use the bundled DejaVu Sans for fair text-fidelity comparison.

svg2png v0.2.0 inherits all of the above through its ProjectReference to the library. The single AOT-published native binary stays at ~10 MB and remains the smallest cross-platform SVG rasterizer in the .NET ecosystem.

v2.5.0 — 2026-04-11

Added

• Mostlylucid.ImageSharp.Svg — a small, low-allocation, AOT-clean SVG rasterizer built on SixLabors.ImageSharp. Lives at the repo root as a standalone library (~1100 lines, 7 files). No SkiaSharp, no native binaries, no reflection. Hand-rolled XmlReader-based parser → AST → ImageSharp draw calls. Honours the cascade for inheritable presentation attributes (<g> parents, style="", CSS class selectors from <style> blocks), parses every CSS color form (hex, named, rgb(), rgba(), hsl(), hsla()), supports viewBox, transforms (translate/scale/rotate/skew/ matrix), and the full SVG element subset that shields.io and Naiad/mermaid emit (rect/circle/ellipse/line/path/polygon/polyline/text/g). Publishes clean under dotnet publish -p:PublishAot=true — verified at 1 MB native dylib, zero trim warnings.
• svg2png AOT command-line tool (released separately, see the svg2png-v0.1.0 release). Single 9.7 MB native binary, no .NET runtime required. Reads SVG from disk or stdin, writes PNG to disk or stdout, supports --scale, --background, --quiet. Built from the new Mostlylucid.ImageSharp.Svg.Cli project. Cross-platform: win-x64, linux-x64, osx-x64, osx-arm64.
• Local SVG markdown images are now rendered through the new managed rasterizer. MarkdownService.ProcessImagePaths detects .svg paths and routes them to ImageCacheService.CacheLocalSvg, which converts to PNG via Mostlylucid.ImageSharp.Svg and rewrites the markdown to point at the cached PNG. Cache key includes the source file's mtime so editing the SVG on disk re-renders automatically on the next document open.
• Animated GIF / WebP / animated PNG playback in the markdown renderer. LiveMarkdown.Avalonia uses Avalonia's static Bitmap for images which only decodes the first frame, so animated formats appeared as one static frame. Added AnimatedImage.Avalonia and a post-render visual-tree visitor that finds Image controls in the document and promotes the ones whose markdown source URL is *.gif|*.webp|*.apng to the animated source via ImageBehavior.SetAnimatedSource. Loop count is respected via RepeatBehavior.Default (the file's embedded loop count). Verified end-to-end via ux-scripts/verify-gif-playback.yaml — captures four frames spaced 600ms apart and confirms the md5s differ.
• Restart-animation overlay button on each animated image. 28×28 circular button in the top-right corner of the image, attached via the visual tree alongside the image. Click → clears AnimatedSource and immediately re-sets it, restarting the animation from frame 0. Pause/resume isn't possible because AnimatedImage.Avalonia doesn't expose a public play/pause API; clearing AnimatedSource would blank the image, which is worse than no pause at all.

Changed

• Five SKSvg sites in lucidview replaced with the new managed rasterizer:
  • ImageCacheService.ConvertSvgToPng (shields/badges)
  • MarkdownService.RenderMermaidToPng (in-app mermaid PNG fallback)
  • MarkdownService.ExportMermaidToPngBytes (PDF export pipeline)
  • FlowchartLayoutBenchmark.RenderFullPipeline (test harness)
  • Local .svg markdown image loading (was previously handled by LiveMarkdown.Avalonia.Svg.Skia)
• Svg.Skia and the LiveMarkdown.Avalonia.Svg.Skia plugin removed from MarkdownViewer.csproj. The entire Svg.Skia / Svg.Custom / Svg.Model / ShimSkiaSharp family is gone from the resolved dependency graph (dotnet list package --include-transitive confirms this for both MarkdownViewer and MarkdownViewer.Tests). Trims a meaningful chunk of the Release single-file payload — the new Mostlylucid.ImageSharp.Svg.dll is 31 KB, replacing several MB of Svg.Skia + ShimSkiaSharp + Svg.Custom + Svg.Model.

Fixed

• Shields/badges no longer render at column width. Two distinct bugs were collapsing into the same visible symptom. (1) The cache rewriter was emitting file:// URIs for resolved cache paths, which LiveMarkdown's LocalFileAsyncImageLoaderHandler silently rejects — fixed by emitting plain absolute paths. (2) PNGs cached at 2× their intrinsic size for hi-DPI crispness were being displayed pixel-for-DIP by Avalonia, doubling on-screen size — fixed by ImageCacheService recording the SVG's natural 1× dimensions and a post-render visual-tree walker (MainWindow.ScheduleConstrainCachedImages) setting Width/ Height on each cached Image control to the natural size, so the bitmap downscales at composite time and looks crisp.
• Shields re-fetch on every document open. Added ImageCacheService.InvalidateInMemoryCache(), called from LoadFile/LoadFromUrl so dynamic shields (build status, latest version, downloads) reflect the current state instead of whatever was cached when the app started.

v2.2.4 — 2026-04-11

Fixed

• Open File / Save File / Export PDF / Export Diagram dialogs no longer stack on top of each other. macOS was firing the click path AND the IActivatableLifetime.Activated event in the same flow, opening two pickers — the second one underneath the first and unclickable. Added a _filePickerOpen re-entry guard around every StorageProvider call so the dialog is one-at-a-time regardless of which path triggered it. Applies to: OpenFile, ExportPdf, ExportMermaidDiagram, ExportAllMermaidDiagrams, SaveDiagramAs.

v2.2.3 — 2026-04-11

Changed (rip and replace, not patch)

• Ruler architecture rewritten — alignment is now layout-driven, not math. Ripped out the entire UpdateRulerHandlesFromWidth / TransformToVisual / RulerCanvas / scrollbar / gutter / scale / fallback math. The ruler bar is now a Grid inside the LayoutTransformControl, in a StackPanel above the document Border. The bar's Width is bound to the Border's Width via XAML ElementName binding, so they are always the same logical width. Handles use HorizontalAlignment=Left/Right with negative margins to extend slightly past the column edges. Avalonia's layout engine handles every alignment concern: scrollbar, centering, scale transform, gutter, padding — all gone, all replaced by one ElementName binding.
• Code-behind shrank from ~230 lines to ~85 lines. The remaining handlers do exactly three things: change Border.Width on drag, change Border.Width on click, update the readout text.
• Zoom slider, font size, fit modes — they all "just work" because the ruler is inside the same LayoutTransformControl as the document, so it scales with the column automatically. No RefreshRulerForScaleChange plumbing required.

Verified

• Release build does NOT include Mostlylucid.Avalonia.UITesting. The Debug-only Condition="'$(Configuration)' == 'Debug'" on the <PackageReference> is honoured by MSBuild and obj/Release/ contains no UITesting traces. The recent ~5 MB Release size growth (~73 MB → ~78 MB) is from FluentAvaloniaUI which IS a Release dependency, added in v2.1.1 for the polished button styling.

v2.2.2 — 2026-04-11

Fixed

• Ruler handles align with the actual card outline at every scale. The Border had HorizontalAlignment="Center" which made it shrink to fit the content's natural width rather than honour MaxWidth. So the visible card was sitting at the content width (e.g. 616px), not the configured 900px column, and the handles were correctly placed on the configured edges — which were nowhere near the visible card edges. Switched to Border.Width = ContentMaxWidth (an explicit width, not a cap) so the Border is forced to the column width regardless of content.
• Width persists immediately on drag. OnRulerHandleDragDelta now calls _settings.Save() after each delta. The settings file is tiny so the write cost is negligible. Survives unexpected app exit, not just a clean window close.

Changed

• Mostlylucid.Avalonia.UITesting is now consumed via NuGet (1.1.0) instead of a <ProjectReference> to the local lucidRESUME working tree. Decouples the lucidVIEW Debug build from in-progress lucidRESUME edits. The package is still gated to Debug-only so Release builds stay tiny and AOT-friendly.

Internal

• Added a LUCIDVIEW_RULER_DEBUG=1 environment variable that prints the computed ruler alignment values to Console.WriteLine on every layout update. Avoids having to record large GIFs to diagnose alignment drift.
• All ruler logic now reads/writes MarkdownContentBorder.Width instead of .MaxWidth (drag handler, click handler, scale refresh, layout subscription, width readout).

v2.2.1 — 2026-04-11

Fixed

• Ruler handles now sit exactly on the visible Border outline at all zoom levels. Replaced the hand-rolled position math with TransformToVisual(MarkdownContentBorder → RulerCanvas) so the handles use the actual rendered geometry of the card edge. No more drift from scrollbar widths, content alignment, ScaleTransform, gutter padding, or inner Padding offsets — the ruler asks Avalonia where the Border is.
• Removed the dotted ghost guides entirely. The card border itself is the only vertical reference now. The user complaint was that the dotted guides and the visible border were two different lines that drifted out of alignment; now there is exactly one line.
• Document no longer jumps to the right when zooming out. RenderedScroller got HorizontalContentAlignment="Center" and MarkdownLayoutTransform got HorizontalAlignment="Center" so the centred Border stays centred regardless of how the LayoutTransform scales it. Previously the ScrollViewer aligned the shrunken content to top-left.
• Ruler is now zoom-aware. GetMarkdownScale() reads the live ScaleTransform from MarkdownLayoutTransform and the ruler math multiplies by it when positioning handles. The handles follow the visible text edges as the user changes font size or zoom slider, not the unscaled logical width.
• Click-anywhere-on-the-ruler snaps the column width to that point. Both edges move symmetrically since the column is centered. Lets the user set the width with one click instead of fiddling with two handle drags.
• Built-in MainWindow ruler now updates whenever the Border bounds change via a BoundsProperty subscription on MarkdownContentBorder. Window resize, font-size change, zoom slider, manual MaxWidth — all trigger an automatic re-position.

Internal

• OnRulerHandleDragDelta now divides the drag vector by the current scale, so dragging in window pixels translates to the right delta on the underlying logical MaxWidth.
• Padding bumped from 40→48 to give the new card border breathing room around the text, with the math constant updated in lock-step.
• Two upstream errors fixed in Mostlylucid.Avalonia.UITesting: Pointer ambiguity in PointerSimulator.cs (qualified to global::Avalonia.Input.Pointer) and unimplemented MCP wheel/pinch/ rotate/swipe/touch handlers (stubbed as “not implemented yet” instead of unresolved methods).

v2.2.0 — 2026-04-10

Added

• README rewrite — actually showcases lucidVIEW now. Hero screenshot, 6-theme gallery from the user manual, copy-paste install commands per platform, full keyboard-shortcut table, link to the in-app user manual. The Naiad fork section is still there but moved below the lucidVIEW feature pitch.
• Subtle document border — MarkdownContentBorder now has a 1px AppBorderSubtle outline + CornerRadius="4" + 16px vertical margin. Document looks like a card now instead of text floating in space. The border colour is per-theme so it's barely-visible brightening on dark themes and barely-visible darkening on light themes.
• ux-scripts/capture-ruler.yaml — UI test that toggles the ruler on/off and captures the two states for the user manual.
• New section 11. Word-style ruler in the in-app User Manual, with the ruler-off and ruler-on screenshots. Subsequent sections renumbered 12–19.

Fixed

• Ruler handles now sit at the actual text edges, not the Border edges. Previously the MarkdownContentBorder had Padding="40,32" so the handles appeared with a ~40px gap on each side of the column they were supposed to resize. Ruler math now subtracts the horizontal padding when placing the handles, the highlighted track, the width readout, and the dotted side guides. Padding was also bumped from 40→48 to match the new card border.
• Ruler bar now spans the full window width. Was being truncated by the 18px left gutter; reordered the DockPanel so the ruler is docked Top before the gutter claims its space. The gutter still appears under the ruler in the document area.
• Image scaling regression — re-added StretchDirection="DownOnly" alongside Stretch="Uniform". Large images shrink to fit the column, small badges stay at natural size (no more bloat).

Changed

• Document border — MarkdownContentBorder got a 1px BorderBrush="{DynamicResource AppBorderSubtle}" outline, CornerRadius="4", and a 16px vertical margin. Gives the document a card feel so the text doesn't look like it's floating in space. The AppBorderSubtle brush is per-theme so the outline is barely-visible brightening on dark themes and barely-visible darkening on light themes.
• Border padding bumped from 40,32 to 48,40 to give the new outline a little breathing room around the text.

Internal

• .gitignore now ignores .idea/ (and **/.idea/) and .DS_Store folders properly. The 10 stale .idea/*.xml files in lucid.viewer/ that had been tracked by mistake are now untracked (kept on disk).

v2.1.1 — 2026-04-10

Added

• FluentAvaloniaUI adopted as the base theme. Buttons get proper hover/press feedback, the side panel and header look notably more polished. ContentDialog available for future Settings dialog upgrade.
• FluentIcons (Microsoft Fluent UI System Icons) replace the hand-curated boxicons set. 1,800+ icons available via <ic:SymbolIcon Symbol="..."/> — themed automatically, scale via FontSize, no inline path data.
• Word-style ruler above the document with two draggable margin handles and dotted vertical column guides. Toggle via the ruler button in the header. Drag a handle to live-resize the content column; the new width persists to AppSettings.ContentMaxWidth. Default off.

Fixed

• macOS Open With — double-clicking a .md file in Finder launched lucidVIEW but never loaded the file. Wired up IActivatableLifetime.Activated so file paths delivered via Apple Events reach LoadFile(). Same hook handles iOS / Android / Linux MIME activation.
• Image cropping — <Style Selector="Image"> was setting Stretch=None which clipped any image wider than the column. Now uses Stretch=Uniform so images scale to fit the column width without cropping, preserving aspect ratio.
• ContentMaxWidth setting is now actually honoured. Previously the XAML hard-coded MaxWidth=1200 and ignored the persisted value.

Changed

• Open URL HTTP client User-Agent bumped from lucidVIEW/1.0 to lucidVIEW/2.1. The Accept: text/markdown header is preserved (priority q=1) so Cloudflare URL→markdown conversion, Jina Reader, and similar services return markdown instead of HTML.

• Font selector in Settings dialog stops showing the raw avares://lucidVIEW/Assets/Raleway-Regular.ttf#Raleway, Segoe UI, ... URI as a dropdown entry. The bundled Raleway is now listed as "Raleway (bundled)" at the top, the URI is parsed back when saving. Each font name in the dropdown is rendered in its own typeface (Word/Office style live preview) via FontFamily="{Binding}" on the ItemTemplate TextBlocks. Same fix applied to the code font dropdown.

Internal

• New Styles/Icons.axaml removed — replaced wholesale by FluentIcons.
• Border wrapping the markdown is now named MarkdownContentBorder so the ruler can manipulate its MaxWidth.
• New MainWindow regions: File Activation (Open With handler) and Word-style Ruler (drag math + persistence).
• MainWindow.axaml.cs got an Avalonia.Controls.ApplicationLifetimes using.
• SettingsDialog.ExtractDisplayName() parses FontFamily strings (avares URIs, comma-separated lists, plain names) into clean dropdown labels.

v2.1.0 — 2026-04-10

Added

• Self-documenting in-app User Manual (F1) — bundled at manual/user-manual.md next to the binary, with 17 screenshots automatically captured by the UI testing harness via ux-scripts/capture-manual.yaml. The manual covers every feature with real screenshots that always match the current build. Re-generate by running the capture script. Shift+F1 still opens the README.
• Pride theme — a celebration palette using the Pride flag colors as borders, accents, and section dividers. Tasteful enough to read code in, bright enough to show off.
• Configurable custom theme — define your own palette in settings.json under customTheme and select Custom from the side panel. See default-settings.json for the schema and a Solarized-ish example. The Custom theme card only appears when a custom theme is configured.
• UI polish — header bar got a 2px accent-coloured bottom border, font A buttons are now grouped in a rounded pill with proper spacing instead of cramping against the macOS window controls.
• Real Print function (Ctrl+P) — sends the current document to the OS default printer. Generates a temp PDF via QuestPDF then hands it to ShellExecute (print verb) on Windows or lp (CUPS) on macOS/Linux.
• macOS .app bundle — pwsh ./publish.ps1 -Platform osx now produces lucidVIEW.app with proper Info.plist, Resources/lucidVIEW.icns, ad-hoc codesigning, and file-type associations for .md / .markdown / .mdown / .mkd. Double-clicking the bundle launches the GUI directly with no Terminal window and a Dock icon. Both osx-x64 and osx-arm64 are produced. The release CI workflow assembles the same bundle.
• Windows Store (MSIX) prep — pack-msix.ps1 produces a signable publish/store/lucidVIEW.msix ready for Partner Center upload. The Package.appxmanifest now uses build-time identity tokens, the MarkdownViewer/Assets/Store/ folder ships eight tile/logo PNGs, and a manual-dispatch store-publish.yml GitHub Actions workflow builds the MSIX on windows-latest. Full setup walkthrough in docs/windows-store.md.
• UI testing harness (Debug only) — Wired up Mostlylucid.Avalonia.UITesting via --ux-test, --ux-repl, --ux-mcp startup flags. Three YAML scripts in ux-scripts/ exercise every non-dialog function, every dialog, and the hand-driven REPL/MCP modes. The harness is excluded from Release builds via a Debug-only <ProjectReference> and #if DEBUG guards — Release binaries stay tiny and AOT-capable.
• NavigateCommand on MainWindow (Debug-only consumer; routes to LoadFile). Lets the YAML test scripts self-bootstrap by loading a fixture markdown file via the standard Navigate action.
• docs/macos-bundle.md, docs/windows-store.md, and ux-scripts/README.md.

Changed

• Ctrl+P is now real Print, not Export PDF. Export PDF moved to Ctrl+Shift+P (also still available via the side-panel menu). The side panel now lists "Print (Ctrl+P)" above "Export PDF... (Ctrl+Shift+P)".
• publish.ps1 adds osx-arm64 and reworks the platform list — osx shorthand now builds both Intel and Apple Silicon variants.
• release.yml workflow assembles macOS .app bundles before zipping the artifacts so downloads launch as GUI apps on the receiving Mac.
• Bumped MaxVersionTested in the Store manifest from 10.0.22621.0 to 10.0.26100.0 (Windows 11 24H2).

Fixed

• Pre-existing build break in Naiad/QuadrantParser.cs: c is not '-' or ' ' parses as (c is not '-') or (c is ' ') which is always true. Corrected to c is not ('-' or ' '). Fixes CS9336 redundant-pattern errors that were blocking all builds on the .NET 10 SDK.
• Pre-existing security warning NU1903 — Tmds.DBus.Protocol 0.21.2 (transitive via Avalonia) had a high-severity vulnerability (GHSA-xrw6-gwf8-vvr9). Pinned to 0.92.0.
• Wrong Executable in Package.appxmanifest — was MarkdownViewer.exe, the real assembly is lucidVIEW.exe. The MSIX would have failed at launch.
• xUnit2013 warning in AvaloniaNativeDiagramRendererPluginTests — replaced Assert.Equal(0, count) with Assert.Empty(...).

Internal

• Refactored PdfExportService — added ExportToTempAsync so the new Print path can hand a temp PDF to the print service without duplicating the PDF-build logic.
• Added MarkdownViewer/Services/PrintService.cs.
• All MSBuild changes that reference UITesting are conditional on '$(Configuration)' == 'Debug' so the Release pipeline doesn't even see the testing harness.
• Fixed UseUITesting() upstream bug in Mostlylucid.Avalonia.UITesting: the extension hooked AfterSetup which fires before App.OnFrameworkInitializationCompleted sets MainWindow, so UITestingStartup.AttachToApplication would silently bail. Re-routed through the IClassicDesktopStyleApplicationLifetime.Startup event so the harness only attaches once MainWindow actually exists. Without this fix every --ux-test/--ux-repl/--ux-mcp invocation was a no-op.
• ThemeService learned to render a runtime ThemeDefinition (not just the static built-ins), used for both AppTheme.Custom and any future config-driven themes.
• MainWindow.NavigateCommand (Debug-only consumer) routes the YAML Navigate action to LoadFile.
