/* ============================================================
   Stella Apps — brand system (tokens + base + components)
   Lifted from Dave's two locked artifacts, 30 Jul 2026:
     "Stella Apps — Brand template"  (the one-sheet)
     "Stella Apps — small software for people who make things"
   Every value here is the brand template's, verbatim, with ONE
   documented addition: two darker TEXT-ONLY tokens, because the
   originals fail measured WCAG AA when used as text on cream —
   gold-deep #B8860B is 2.82:1, bronze #A5713A is 3.62:1
   (measured 31 Jul 2026; AA needs 4.5:1 for normal text).
   Fills, rules and every other value are untouched.
   Page-layout CSS lives inline in each page; this file is only
   the reusable system.
