docs(media): keep video off GitHub, document where media lives

Only GIFs that a public page embeds stay in docs/images/: the five README
GIFs plus subagent-demo-20260724.gif, which the published "mission control"
article hotlinks from master. Seven GIFs nothing embeds leave the tree
(their masters are kept in the maintainer's local media library).

.gitignore now blocks *.mp4/*.webm/*.mov/*.m4v/*.mkv/*.avi/*.gif outside
docs/images/*.gif (and the promo branch's Remotion inputs), so a video can
only be committed with an explicit `git add -f`.

docs/media-assets.md records the rule: what is tracked and where it is
embedded, website media (pr/website/assets, deployed separately), release
clips on the design-assets branch, and the local library layout.

 **`npm test` is the gate and is safe to run bare** — it runs `config/vitest.ci.config.ts`, exactly what CI runs, so local green means CI green.

+# Media assets: videos and GIFs
+
+Codeman produces a lot of video: README GIFs, website loops, release-note clips, promo videos and their drafts, raw screen captures. This page says where each kind lives and which of them belong in git.
+
+## The rule
+
+**Only media that a public page embeds is pushed to GitHub. Everything else stays on the maintainer's machine, in the local media library.**
+
+| Kind | Where it lives | On GitHub? |
+| --- | --- | --- |
+| GIFs the README, the wiki or a published article embeds | `docs/images/` on `master` | yes |
+| Release-note and media-kit clips | the orphan `design-assets` branch | yes, but never on `master` |
+| getcodeman.com videos and GIFs | `pr/website/assets/` (local, deployed to Cloudflare Pages) | no |
+| Masters, promo videos, drafts, shorts, feature clips, raw captures | `pr/media/` (the local media library) | no |
+| Remotion render inputs for the promo videos | `scripts/remotion/public/` on the unpushed promo branch | no |
+
+`.gitignore` enforces it: `*.mp4`, `*.webm`, `*.mov`, `*.m4v`, `*.mkv`, `*.avi` and `*.gif` are ignored everywhere except `docs/images/*.gif`, plus `scripts/remotion/public/`, whose render inputs the promo branch tracks. A video that really must be committed needs `git add -f`, which makes the exception visible in review.
+
+A GIF that leaves `docs/images/` stays in git history, so removing it does not shrink a clone. The rule keeps new weight out and the tree honest about what is actually used.
+
+## Tracked GIFs (`docs/images/`)
+
+| File | Embedded in | Shows |
+| --- | --- | --- |
+| `tiles-crt-stats-1600-20261010.gif` | README hero (en + zh-CN) | six live agents in the tile grid, powering on and off with the CRT animation, header stats on |
+| `tile-grid-20261009.gif` | README, Tile Grid section | the Tiles button opening six live sessions side by side, and closing them |
+| `zerolag-demo-20260728.gif` | README, wiki `Input-And-Voice`, `packages/xterm-zerolag-input/README.md`, CHANGELOG, getcodeman.com docs | instant local echo next to slow server echo, on two phones |
+| `codeman-tab-states-20261010.gif` | README, Tab Alerts section | annotated tab states: working, blocked on a question, idle |
+| `codeman-skill-crt-20261010.gif` | README, agent skill section | one prompt to Claude Code spawning and driving two worker sessions through the skill |
+| `subagent-demo-20260724.gif` | the "mission control" article on dev.to, Hashnode and Medium (hotlinked from `master`) | subagent windows fanning out |
+
+Before removing one, search for hotlinks: `README*.md`, `docs/wiki/`, `packages/*/README.md`, `CHANGELOG.md`, the site (`pr/website/`), and published articles, which link `raw.githubusercontent.com/Ark0N/Codeman/master/docs/images/<file>` and break silently.
+
+On 2026-10-13, seven GIFs that no page embedded left `docs/images/` and moved into the library: `codeman-demo.gif`, `codeman-skill-20261010.gif`, `subagent-demo-new.gif`, `subagent-demo-opt.gif`, `tab-alerts-glow-20260815.gif`, `tiles-crt-20261010.gif`, `tiles-crt-stats-20261010.gif`.
+
+### Adding or replacing a README GIF
+
+1. Keep the master (the lossless MP4 or the full-size GIF) in `pr/media/clips/<feature>/`, or in the project folder it came from.
+2. Commit only the size the README shows, named `<feature>-<YYYYMMDD>.gif`, and keep it lean: the current ones are 0.8 to 7 MB.
+3. A replaced GIF leaves `docs/images/` in the same commit, unless something outside the repo hotlinks it (see above).
+
+## Website media (getcodeman.com)
+
+The site is built and deployed from `pr/website/` (gitignored) with `pr/deploy-site.sh`. Its videos and GIFs sit in `pr/website/assets/` because that directory is what gets uploaded: they are web cuts (1280 to 1600 px wide, high CRF, posters next to them) derived from masters in the library. `pr/site-notes.md` records how each one was cut and from which master. A few superseded files stay deployed on purpose, so links that point at them keep resolving.
+
+## Release notes and the media kit (`design-assets` branch)
+
+GitHub releases and the Announcements discussions embed clips from the orphan `design-assets` branch (`release-1.40/`, `release-1.41/`, `media-kit-2026-10/`). They are referenced by a commit-pinned raw URL, so the branch can change later without breaking old notes, and none of it ever touches `master`.
+
+## The local media library (`pr/media/`)
+
+`pr/` is gitignored, so the library is never pushed. It holds every master, every finished promo cut and every superseded draft in one tree:
+
+```
+pr/media/
+  README.md          curated guide: what each collection is, which cut is current, where it is published
+  INVENTORY.md       generated list of every file (size, length, resolution, fps, date, published-or-not)
+  inventory.mjs      regenerates INVENTORY.md: node pr/media/inventory.mjs
+  videos/<production>/        finished promo videos; superseded renders in drafts/
+  shorts/<episode>/           per-feature cuts of a promo; older sets in drafts/
+  clips/<feature>/            feature loops and GIF masters (README / site / release clips start here)
+  crt-gifs/                   CRT tile-animation loops
+  files-one-click-20261011/   the Files panel loop project (own README)
+  screenshots-hq/             high-res stills and their capture masters
+  raw-captures/               unedited screen recordings, safe to prune
+```
+
+Two working directories keep files the library only archives, because tools read them from fixed paths: `pr/website/assets/` (the deploy upload) and the promo worktree's `scripts/remotion/public/` (Remotion's `staticFile()` inputs). Renders still land in `scripts/remotion/out/` and are filed into `pr/media/videos/<production>/` once checked. A finished render never goes to `tmp/`.
