/* ---- Homepage (2026-10-19): the Trunk Tools layout in SubPro colours -------
   Loaded by index.html only, after styles.css. The header and footer markup
   stay canonical (tools/sync-chrome.mjs copies them to every page), so this
   sheet restyles them under body.home-page instead of replacing them.
   Every class this sheet owns is prefixed th- so nothing here collides with
   the design system in styles.css.

   Measurements come from trunktools.com as scraped on 2026-10-19: 86rem
   container, 1.5/2/3rem gutters, 6/7.5/8.5rem section rhythm, Poppins 600
   headings at 60/48/36, IBM Plex Sans body, pill buttons, 16px card radius,
   hairline borders. Jay, 2026-10-19: the site may carry ambient motion; the
   rotating hero line, the logo marquee, the fade up on scroll and the stat
   count up all stay. Every one of them still stops under
   prefers-reduced-motion. Design notes: docs/prototypes/2026-10-19-trunk-style-home/README.md */
