/* ════════════════════════════════════════════════════════════════════
   pChisel platform design tokens — single source of truth
   ════════════════════════════════════════════════════════════════════
   Edit /home/pchisel/design-tokens/tokens.css then run sync.sh to copy
   into chisel-base/frontend/ and pchisel-app/frontend/.
   Both codebases @import './tokens.css' from their local copy.

   Canonical names are prefixed --pc-* (pchisel) to avoid collisions
   with the existing --bg / --accent / --text vars in chisel-base
   style.css and the four pchisel-app CSS files. This is a deliberate
   choice for the per-surface rollout (PWR1-PWR16): each surface pass
   replaces its local var references with --pc-* counterparts, so no
   surface gets restyled before its scheduled pass.

   Mobile-specific layout sizes (header / nav / peek heights) intentionally
   differ from the desktop equivalents and are prefixed --pc-mobile-*.
   The legacy --m-* alias block was removed during D0 of the IDE desktop
   overhaul (2026-05-20). mobile.css and mobile.js now reference --pc-*
   tokens directly.

     Glass is part of the pChisel platform identity — it's used on the

     variants for different backdrop conditions:

     --pc-glass-bg          (light translucent, for DARK backdrops):
       used by the mobile chat surface where terminal animations bleed
       through, and by the IDE chrome (chisel-base) overlay variant.

     --pc-glass-bg-platform (semi-opaque white, for LIGHT backdrops):
       used by the unified-nav rail/sidebar on platform pages. The
       rgba(250,250,250,0.18) flavour was functionally invisible against
       the light dashboard bg, so this variant is more present while
       still letting some page-bg show through behind backdrop-filter.
