README: show the slider promo; keep the promo sources - #9
Conversation
The README's video is now the square cut of the slider promo: a feed with a score beside each post, folding as "Hide from" and "Sure from" move. The GIF is 2.4 MB, down from 7.6 MB, and the full-quality links point at the 0.5.1 square and widescreen renders. The 0.2.0 videos it replaces are removed. The generator for the 0.2.0 video was never committed and could not be rerun. The sources for these are: promo/*.html are seekable pages, and promo/record.mjs steps through one frame by frame and encodes an MP4 (needs playwright and ffmpeg). Renders stay out of the repository.

Add playwright as a development dependency.
Bruce found the smoking gun: this direct import is not declared in the supplied package manifest. After a fresh bun install, bun promo/record.mjs fails before it renders a frame. Add playwright to devDependencies.

Correct: playwright is imported but not declared, so a fresh install can't run the script. It's a promo tool, not part of the extension, so nothing shipped is affected, but the point of committing it was to be able to rerun it. Fixing in a follow-up PR rather than holding the README change.

@tshmieldev, understood. The missing playwright declaration is the smoking gun for rerunning promo/record.mjs after a fresh install. Deferring it does not affect the shipped extension or the README media update.
Would you like me to open a follow-up GitHub issue for adding playwright to devDependencies?

Create the file URL with pathToFileURL. Bruce found the smoking gun: interpolation leaves # and ? as URL delimiters and leaves % available for percent-decoding. When PROMO_DIR contains these characters, page.goto can load the wrong file or fail. Use URL.searchParams to add still.
Suggested fix
-import { fileURLToPath } from 'node:url';
+import { fileURLToPath, pathToFileURL } from 'node:url';
- await page.goto(`file://${path.join(here, `${name}.html`)}?still`);
+ const url = pathToFileURL(path.join(here, `${name}.html`));
+ url.searchParams.set('still', '');

Valid but narrow: it only bites when the folder path contains #, ? or %. Three lines with pathToFileURL, so taking it in the same follow-up PR.

@tshmieldev, acknowledged. The issue is narrow, but pathToFileURL removes the file-path parsing risk. The smoking gun remains valid for paths that contain #, ?, or %.
