/* ============================================================
   TIMELINE & DICTIONARY — shared styles
   g-mac-digital-garden v10.1

   Built on the theme's existing design tokens (theme.json palette +
   font families) rather than a new palette. Reads the same
   --wp--preset--color--* custom properties the rest of the site uses,
   so day/night toggling (body.dark, in style.css) applies here for
   free — no separate dark-mode block needed.

   Two header-offset custom properties are set by timeline-dictionary.js
   at runtime, since the site header is position:sticky and its height
   is responsive (the nav wraps on narrow screens):
     --gmac-header-h   height of the sticky site header
     --gmac-toolbar-h  height of the dictionary's sticky search/A-Z bar
   Both default to 0px so the page still works sanely with JS disabled.

     stay visible through these two pages the same way it does elsewhere on
     the site, not get fully masked by a flat content background. Very faint
     over the main scroll area (G's own call, 2026-10-03: the first pass at
     86% read as still basically opaque); the two sticky bars stay a little
     more solid than that so scrolled-past content doesn't show through them
