/*
 * The Library (docs/design/2026-08-12-library-design.md), master-detail
 * (owner: "I think the library needs a master/detail view") — the Notebook
 * shell's grammar in the same tokens: one elevated viewport-fit card split
 * into a master rail and a detail pane, each owning its own scroll. The rail
 * sits a tonal step below the pane so the selected row's lift off its 3px
 * teal edge reads. Rows are list grammar (one line, may ellipsize); the
 * pane never truncates — essays whole, synopses whole.
 *
 * Below 900px it collapses list-first: the rail fills the screen and
 * .is-detail-open (server-set for explicit ?entry= links, client-set on row
 * taps) pushes the pane full-screen with a back affordance.
 *
 * Tokens only; squared corners; motion tokens. Covers are committed files
 * or the designed spine fallback — nothing external at render.
