/* Weave Sprint hub route styles. Links after tokens.css, uses only shared
   tokens, and is loaded by exactly one page: /sprint/.

   BRANDCRAFT v4, batch 2 lane L-B. The idiom is the library cluster (DEC-002):
   /sprint is a shelf of books, and library/index.html is the living precedent
   for presenting books. The vitrine, hallmark, book-render and shelf-card
   PATTERNS are ported here rather than reused by reference: library.css is
   route-scoped to /library/ and is not loaded on this page, so every rule the
   markup needs is restated below.

   Stock: one continuous green sheet (--paper-green) from the hero through the
   rights band, torn into at the top, torn out of above the crisis block. The
   search band is a white card floating ON the sheet, not a sheet change: the
   chrome needs scanning contrast, the page does not need another seam.

   Legibility, measured, both themes. On the light green sheet only --ink
   clears the body floor (7.08:1); --ink-2 is 3.88 and the house --marker is
   1.94. So nothing on the sheet runs anything but ink, and the one accent is
   --sp-accent-ink #6B2A16, measured 4.91 on the green and 10.67 on white.
   Dark theme keeps --marker, which measures 5.58 on the deep green and 6.61
   on the dark card. Same ratified per-lane pattern as --lib-accent-ink.

   Rotation: containers only, and only three of them. The hero art plate, the
   two pen annotations, and the fact stamps. Vitrines, shelf cards, chips and
   the rights band are all 0deg: dense reference surfaces and live controls,
   the same ruling library gave its own vitrines and shelf.

   Shadows are the offset-solid ink tint from tokens, never blur glows.
   No dashed or dotted rule is declared anywhere in this file. */
