/* ==========================================================================
   CLOISTR.IO — the site stylesheet. Every page links this file first; a page's
   own <style> (if it has one) only holds CSS for components unique to it.

   1. BASE   structure shared by the pages. Generated from what used to be
             inlined on all 54 pages (consolidated 2026-10-08). Rules that only
             some page types need are limited with a zero-specificity
             :where(.pg-home / .pg-tool / .pg-post / .pg-blog) on <body>.
   2. THEME  the Ledger look. It comes second, so on equal specificity it wins.
             Tokens get their values per context:
               ground  the page itself (indigo in dark, off-white in light)
               band    nav + page header (always indigo, white text)
               card    detail surfaces (dark card / white card)
               slab    the result block (always dark, holds the amber number)
             Amber (--key) is reserved for the one number that matters and the
             main button. Everything "selected" or "linked" is violet (--accent).
