/*
 * /search — the site search page. Added 2026-09-04.
 *
 * Every colour, space and measure here is a design-system token
 * (docs/04_ICE_DESIGN_SYSTEM.md). Nothing is a literal, so the page follows
 * light and dark without a second rule set: the graphite dark theme moved the
 * accent inks in August 2026 and any hard-coded colour here would have had to
 * move with it by hand.
 *
 * Scoped under .page-search throughout. AGENTS.md's UI evidence gate bans broad
 * element selectors that can leak into shared chrome, and a page whose whole
 * job is an <input> and a <ul> is exactly where that mistake gets made.
 */

/* ⚠️ NO SECOND CONTAINER. This declared `max-width: var(--ice-container)` and
   `margin-inline: auto`, and `--ice-container` is 1280px while the managed
   shell is 1360px with 32px gutters (edulibrary-brand.css). At any viewport
   wide enough to reach the cap, the shell gives its column 1,296px and this
   rule then took 1,280 of them and centred it — so the h1, the input and every
   result card on /search sat 8px inside the brand mark, the rail and the footer
   directly above and below them, on this route and no other (D-01, T-08). The
   shell is the only thing that decides this page's width now. */
