/* Sylph sub-pages: the "Held Breath" chrome for the document pages.
   assets/held-pages.css v131, 2026-09-13. Always loaded AFTER assets/held.css?v=131.

   held.css owns everything that carries a colour: the tokens, the six sky tints, the fixed dusk
   sky, the nav band, the footer pane, the PANE scrim, the focus rings, ::selection and the skip
   link. This file adds only the document layout and declares no colour that is not a held.css
   var, so the tokens still live in one place.

   These pages are the home page held still: the same .sky markup with the mote canvas left out,
   and --depth never moves off 0 so .deep stays transparent. NO canvas, NO GSAP, NO motion and
   nothing to reveal. The only script on a sub-page is a one-line head snippet that mirrors the
   sky tint the visitor picked on the home page; with JS off every page is complete and readable.

   Every rule is scoped to body.subpage, so the file is inert if it is ever linked from the home
   page. The single exception is the reduced-motion rule at the foot, which turns off the smooth
   scrolling held.css sets on <html> (on the home page held.js does that by adding html.rm, and
   there is no script here to add it).

   CONTRAST PROOF: tools/contrast.py in the site repo, which carries the sub-page pairs in all SIX
   tints and must exit 0. The only new ground this file introduces is
     LOGCARD  .log-entry  rgba(14,21,35,.72) over the PANE scrim  (the home page's .way ground)
   Mirror any colour or surface change here into tools/contrast.py so it exits 0 again. */

   3:1 in contrast.py rather than excused as a hairline the way held.css excuses the .quiet
