/* ============================================================================
   portfolio.css — chrome + theme layers for every page of the portfolio site
   (landing, styleguide, patterns, projects).
   ----------------------------------------------------------------------------
   The BRAND tokens (--signal-*) come from /signal-tokens.css (the shared
   source of truth in ../design, reached via a committed symlink — this file
   never redefines them for dusk). Everything here is one of:
     1. the CREAM theme overrides  — mirrors commute-tracker's light ramp
        (commute-tracker/server/app/static/css/app.css owns those values;
        promote them into a shared file when a second light consumer appears);
     2. EXTENDED palette (--sg-*)  — status / dataviz / map colors documented
        by the styleguide but owned by their apps (provenance noted inline);
     3. site layout & component-replica styles.
   Fonts are self-hosted variable woff2 (same files commute-tracker ships).
