/* Bluesheet landing page — Direction A, "The Sheet".
   Palette, type, and component patterns carried down from
   site/docs/reference/direction-a.html (source of truth). No new colors,
   no new fonts. Contrast pairs reused from the reference:
     ink (#17233c) on paper (#dbe7f2)      ~14:1  (reused: h1/h2, wordmark)
     ink-soft (#2d3b52) on paper (#dbe7f2) ~10:1  (reused: body copy)
   Both far exceed the AA 4.5:1 floor for normal text.

   Font faces live in this file so the page has exactly ONE render-blocking stylesheet.
   OFL license texts are in assets/fonts/OFL-*.txt.
   font-display, by face (measured on 2026-09-20, Lighthouse mobile):
   - Source Serif 4 (body; the hero subhead is the LCP element): `optional`. The LCP text
     never waits on, or is resized by, a late font. A first visit on a slow link keeps the
     Georgia fallback for that page view.
   - Fraunces (headlines) and Courier Prime (labels): `swap`. These two carry the approved
     look, so a first-time visitor must see them. Cost: CLS about 0.03 when they arrive
     (gate is 0.1).
   No font preload: it competed with this stylesheet on a slow link and made first paint later.
