   `/library` — the media manager. HANDOFF-20 lane 20.1, rebuilt by HANDOFF-21
   lane 21.1 (`library/SPEC-manager.md` §v2, RAW 22).

   Nick's reference for the neatness is Spotify's library
   (`_assets/2026-09-10e-spotify-reference-chrome_4q2tJ4GtSN.jpg`). v2 is his
   round 4–6 answers: a tall airy hero with the submenus in it, the controls
   as their own sticky strip, a slim left sidebar of filters on a desktop,
   Spotify squares, and WHITESPACE — "Also mind you I was considering some
   whitespace for the library page."

   The rules this sheet enforces:

     · the page is FULL SCREEN: the rail and the phone tab bar are hidden by
       `.app[data-view="library"]`, and one "Back to app" is the way out;
     · a SECTION IS TWO ROWS. `grid-template-rows` is two and the overflow is
       clipped; `fitRows` (library-page.js) hides what two rows of the real
       auto-fill column count cannot show and puts "+N more" in the last cell;
     · a tile is never wider than the "gallery" allows — auto-fill from
       `--lb-tile`, so its width stays roughly between that and 160px;
     · on a phone a section is ONE strip that scrolls sideways;
     · nothing here may scroll the PAGE sideways. Every horizontal scroller is
       its own `overflow-x: auto` box inside a `min-width: 0` grid cell.
   --------------------------------------------------------------------------- */
