/* ============================================================
   GH HEATING — DESIGN SYSTEM
   ------------------------------------------------------------
   This stylesheet is structured as a reusable component system
   intended to be ported to WordPress Gutenberg blocks.

   PRIMITIVES
     - Tokens (color, type, space, radius, shadow)

   SECTION BACKGROUNDS — five styles only
     .sec-light    #ffffff
     .sec-subtle   #f5f6f8
     .sec-tinted   #eef3f7
     .sec-dark     #1a4c72   (navy)
     .sec-deep     #1e2d3d   (deep blue-gray)

   BUTTONS — three styles only
     .btn-primary    solid orange
     .btn-secondary  outlined orange
     .btn-ghost      outlined white (use on .sec-dark / .sec-deep)

   CARDS — one base + dark inversion
     .card           base white card
     .sec-dark .card,
     .sec-deep .card invert to dark card with light text

   EYEBROWS — single format
     .eyebrow        "— LABEL" small caps, orange dash prefix

   COLOUR RULE — orange is a light-background colour
     On .sec-dark and .sec-deep:
       - All text/headings/icons render in white
       - Orange TEXT/ICON accents use --orange-on-dark (#ff8d4d),
         a lifted tangerine that keeps saturation but passes AA on navy
       - Full --orange (#e95000) only as a FILL behind white text
         (buttons, badges) — never as text on navy
       - Buttons MUST be .btn-ghost (white outline) — never .btn-primary
     On .sec-light / .sec-subtle / .sec-tinted:
       - Orange buttons (.btn-primary) are the default CTA
       - Brand-colour logo, dark text
