feat: rebuild the studio bento on the editor's real controls

[richiemcilroy]

Rebuilds the nine Studio Mode feature cards on the homepage after feedback that the illustrations all looked the same and it was hard to tell where to look.

• Every card now sits on a flat ground with one focal element: the real editor control for that feature, drawn in the desktop editor's current visual system (window, cards, accent, tinted timeline segments) with the app's own labels and defaults.
• Painted wallpapers are gone from the cards, except as swatches in the backgrounds card. The webcam appears only in the Scenes card, where the camera is the subject.
• Uniform 3x3 grid with a single card frame, tighter type, and the last card spanning the row at tablet width. One code-split chunk per card.

Validated: biome and typecheck clean for the folder; per-card, reduced-motion pose, and 390/900/1440px screenshots reviewed; with the section in view 109 fps and no long tasks, 74 fps under 4x CPU throttling.

Greptile Summary

Rebuilds the homepage Studio Mode feature grid around nine code-split illustrations modeled on the editor’s controls.

• Replaces the previous card artwork and layout with a uniform responsive grid.
• Adds shared editor-style primitives and dedicated visuals for masks, scenes, zoom, captions, text, 3D motion, backgrounds, color grades, and clips.
• Removes narrational comments and renames the 3D card file to kebab-case in response to the previous review.

Confidence Score: 5/5

The PR appears safe to merge; the changes since the previous review address both prior repository-rule findings without introducing a new actionable issue.

The narrational comments were removed, and the 3D component was renamed to three-d.tsx with its dynamic import updated accordingly. Both previous threads were manually resolved by richiemcilroy without explanatory replies, and the current code also fully addresses their findings.
