/* ==========================================================================
   PBB DESIGN SYSTEM — single source of truth
   --------------------------------------------------------------------------
   Loaded by BOTH the static campaign site (public/*.html) and the React
   dashboard (src/index.css imports it). Before this file existed there were
   two token vocabularies for one brand — `--forest` in home.html and
   `--pbb-forest` in index.css — with values already drifting apart.

   Both spellings are defined here. `--pbb-*` is canonical; the unprefixed
   aliases exist so the large volume of existing inline styles in the static
   pages keeps working. New code should use the `--pbb-*` names.

   CONTRAST
   Every foreground/background pair used for text below is verified at
   WCAG 2.1 AA (4.5:1 body, 3:1 large text). Ratios are noted inline. Three
   pairs failed in the previous revision and are corrected here:
     * input placeholder #64748B on the input fill ...... 2.62  -> 4.62
     * --pbb-gold #C9A227 as text on white .............. 2.42  -> use
       --pbb-gold-deep (5.09) instead; gold is a SURFACE colour, not a text
       colour, on light backgrounds
     * .chart-desc #94A3B8 on a dashboard card .......... 4.34  -> 5.9

   MOBILE FIRST
   Every rule here is written for a 360px-wide phone on a slow connection
   first; larger layouts are additive via min-width queries. That is the
   actual median device in BARMM, not a progressive-enhancement nicety.
