/* Homepage layout boundary — FULL-BLEED (2026-09-05, supersedes the centered
   v1 of the same day). Loaded LAST and scoped to body.orpho-home, so nothing
   here reaches the 47 other pages that share index.css, and nothing in
   index.css can undo it on specificity.

   Contract:
   * The FRAME goes to the rail. Section grounds, cards, the header row, the
     hero grid and the footer run from --orpho-rail to --orpho-rail at every
     width. Nothing on this page is centred inside an invisible column.
   * COPY keeps a measure. Body text inside those frames is capped in `ch`, so
     the page stays readable at 2560px instead of running 140-character lines.
   * This sheet declares NO grid-template-columns for .orpho-hero__inner,
     .orpho-sample__grid or .orpho-pair. Their columns — and the phone collapse
     in orpho-home.css's TERMINAL BLOCK — stay authoritative. Pinned by
     tests/test_home_layout_fullbleed.py.
   * No `transform` on any ancestor of #hero-envelope (it flattens the
     envelope/receipt z-stack). No `100vw` (includes the scrollbar). No
     overflow-x:hidden on html/body (it kills #sticky-status mid-anchor).
   * Colours, radii, durations come from orpho-tokens.css only.
   * Phase C ornament (corners, ledger ground, connector) is the last block. */

/* ══ Phase C — ornament at the edges (2026-09-05, founder lifted the gate) ══
 * Everything below is decorative and lives in the hero's padding band or
 * beneath the hero grid: nothing here moves the lede, the plate or the
 * buttons, and nothing takes a pointer. Above 1040px only — the one-column
 * hero has no corners to speak of.
 *
 * C2/C3 · ledger rules + edge fade. ONE pseudo-element, two background
 *   layers. body.orpho::before already paints the paper grain, so a second
 *   noise texture would double it; faint horizontal ledger rules give the
 *   hero a ruled-page ground instead, and the paper deepens toward both
 *   edges the way a sheet does under a lamp. z 0, under .orpho-hero__inner
 *   (z 1). Colours: tokens only.
 * C1 · corners. Four <li> in the hero's four corners, in the padding band,
 *   so they cannot collide with the grid by construction (the probe still
 *   measures it). Each has a 1px gold hairline through the rail to the edge.
 * C4 · connector. A hairline from behind the envelope to the right edge, a
 *   block glyph half off the edge (clipped by the hero's overflow:hidden),
 *   one gold point travelling it on the --orpho-m-float clock. No transform
 *   anywhere on an ancestor of #hero-envelope; the dot animates `left`. */
/* Base state is HIDDEN (2026-09-07 review). The ornament used to be styled
 * only inside `@media (min-width: 1041px)` and hidden only inside
 * `@media (max-width: 1040px)`: an exclusive PAIR, so the breakpoint was
 * written twice and the band between the two literals was covered by
 * neither rule. Hiding by default and unlocking once leaves one literal in
 * this sheet and no uncovered width. */
