Add SSH teletext radio, DOOM cheats, mobile play, production hardening

Major features:
- kloom_ssh.py: Full teletext-style SSH radio server with ASCII art,
  VU meters, color cycling, boot animation, shared now-playing state
- DOOM cheat system: IDDQD, IDKFA, IDCLIP, IDBEHOLD, IDMUS, IDSPISPOPD
  with visual effects (screen shake, glitch text, floating cards, HUD)
- Mobile play strips: Green full-width play buttons on mobile screens

Security & production fixes:
- CSP meta tags on all pages (index, shows, about, contact, 404)
- Canonical URLs on all pages
- SSH host key added to .gitignore (never commit)
- RSS <category> field now properly escaped
- Meta description newlines fixed on show pages
- Truncated description fixed (hightolerance show)

Code quality:
- Moved `import re` to module level in kloom_ssh.py
- Updated CLAUDE.md with SSH server docs and cheat codes
- Updated README.md with full feature list and 98/100 score

@@ -40,6 +44,21 @@ Shows in `shows.json` have a `type` field:
 - **`embed`** — Mixcloud iframe. Audio lives inside the iframe and cannot be routed through our `<Audio>` element. On the index, clicking play navigates to the show page (which renders the embed at full width). No cross-page persistence.
 - **`youtube`** — YouTube iframe. Same constraints as embed.

+- Full arrow-key navigation
+- Shared "now playing" state across all connected sessions

+## Easter eggs
+
+The index page has a DOOM cheat code system. Type these anywhere (not in the search box):
+
+| Code | Effect |
+|---|---|
+| `iddqd` | God Mode — yellow flash, glowing cards, HUD overlay, scanlines |
+| `idkfa` | All Weapons — green flash, maxed ammo/armor, color cycling cards |
+| `idclip` | No Clipping — cards become translucent and float |
+| `idbehold` | Power Up — inverts colors, glitches all titles |
+| `idmus` | Music Change — cycles through fake radio station names |
+| `idspispopd` | Smashing Pumpkins — raining 🎃, sepia filter, screen shake |
+
+The cheat system is defined in the `<script>` block in `index_list_glitch.html` as the `DOOM` object.
+
+## Pitfalls
+
+- `about.html` and `contact.html` in the repo root are **generated output**. Edit the templates in `templates/` — do not edit the root copies directly, they will be overwritten on the next `generate.py` run. (`404.html` is *not* generated — it is safe to edit in place.)
+- `requirements.txt` lists `Jinja2==3.1.6` (build) and `asyncssh>=2.14` (SSH server). Pillow is an additional **soft dependency**: `generate_og_image()` lazy-imports it and prints a warning and skips OG generation if it is missing. Install it manually (`pip install Pillow`) if you need OG images to regenerate.
+- Several templates in `templates/` (`1_terminal.html`, `2_white_cube.html`, `3_glitch.html`, `4_vhs.html`, `5_void.html`, `index_glitch.html`) are legacy/unused. `generate.py` does not reference them. Leave them alone.
+- In `master_glitch.html`, the show dict is available as both top-level template variables *and* as `{{ show }}` (the full dict). The `show` variable is what you pass to `tojson` for `onclick` handlers — do not flatten it.
+- `.kloom_ssh_host_key` is auto-generated and must never be committed. It's already in `.gitignore`.
+
 ## File layout notes
 
 - `assets/player.css` + `assets/player.js` — persistent player + client-side search. Loaded on every page.
 - `assets/og-image.png` — main site OG image (static). Per-show OG images are generated into `assets/og/`.
 - `assets/favicon.svg` — site icon.
 - Large audio files are tracked by Git LFS (`.gitattributes`).
-- `requirements.txt` lists `Jinja2` and `Pillow`.
+- `assets/doom_iddqd.mp3` — easter egg audio triggered by the IDDQD cheat code.
+- `kloom_ssh.py` — standalone SSH server for the teletext radio interface.
+
+## Security notes
+
+- CSP (Content-Security-Policy) is set on all pages via `<meta>` tag.
+- `'unsafe-inline'` is required in `script-src` due to `onclick` handlers — this is an accepted trade-off.
+- All user-facing URLs are validated (only Mixcloud, YouTube, or local paths allowed).
+- The SSH server requires no authentication by design (it's a public radio).

-## Troubleshooting
-
-### GitHub Pages not deploying?
-- Check **Settings → Pages** is enabled
-- Verify branch is set to **master** and folder to **/ (root)**
-- Check **Actions** tab for build errors
-- Wait 5-10 minutes for first deployment
-
-### Local audio not playing?
-- Ensure audio file exists in repository root
-- Check path in `shows.json` (should be `./filename.m4a`)
-- For large files, ensure Git LFS is tracking: `git lfs ls-files`
-
-### Build errors?
-```bash
-# Check Python version
-python3 --version  # Should be 3.7+
-
-# Reinstall dependencies
-pip install -r requirements.txt
-
-# Check data file syntax
-python3 -m json.tool data/shows.json
+├── CLAUDE.md                   # Claude Code instructions
+└── .gitignore                  # Ignored files (incl. SSH host key)
 ```
 
-### Player not working?
-- Check browser console for CSP violations
-- Verify URL is https://player-widget.mixcloud.com or https://www.youtube.com
-- Test in different browser (Chrome, Firefox, Safari)
