/* =========================================================================
   PITCH — Coming soon
   The album opening: a closed leather cover that swings open on load into a
   two-page paper spread. Palette/paper-grain match client/css/album.css
   §8/§14 so this reads as a page from the same sticker album. Shared by
   every page on this site: the static ones in public/ and the
   server-rendered confirm page (functions/invite/confirm.js), all of which
   link this same /style.css by absolute path.

/* ---------- Changing-room backdrop: full-bleed, blurred, vignetted ----------
   One background, on `html`, covering the whole document height (not just the
   viewport). `html`'s own box is always exactly as tall as the page content,
   so this can never "run out" partway down a tall page the way a `position:
   fixed` backdrop can — Chromium's own full-page screenshot capture doesn't
   repaint fixed-position layers past the original viewport height, which
   leaves a flat band of the underlying color below the fold. The blur/desaturate
   that album.css normally applies with a CSS `filter` is baked into the image
   asset itself instead (`filter` on `html` would blur the real content too,
   since it applies to the whole box including descendants). No
   `background-attachment: fixed` anywhere — that trick is broken on iOS Safari. */
