/* ==========================================================================
   dulus.ai — dulus.css
   The design system every page loads: tokens, base, layout, components and
   the site-wide pieces (nav, drawer, footer, consent, command palette), in
   that order. No build step, no framework. Styles that belong to one page
   live next to it — home.css, fuel.css, pricing.css … — loaded after this.

   The palette is Brand Kit v1, which is the palette of the golden bird
   itself: #FFD27A → #F5982A → #E0701A, gold #FAD38B, ember #C85C23, on
   #0a0a0b. The site is dark by design — the bird belongs on the night.

   Accent rules, from docs/BRAND_GUIDE.md and the kit:
     · orange is for accents and calls to action, never a section background
     · at most two accent colours in one composition (here: gold + one signal)
     · an accent used as small text uses --gold-ink, which passes AA on --bg
