   nav bar, footer, buttons, section titles, the
   scrolling marquee strip, and the dark page-hero
   banner used at the top of every non-home page.

   🔴 THIS IS THE ONLY FILE WHERE YOU SHOULD CHANGE
      SITE-WIDE COLOURS. Change a value once here and
      it updates everywhere (nav, buttons, footer, etc)
      because every page references these same variables.

   🎨 COLOUR THEME — edit hex codes here to re-theme the WHOLE site
   ────────────────────────────────────────────────────────────
   --cream    : page background colour (the warm off-white behind everything)
   --dark     : near-black used for nav text, dark sections, headings
   --terra    : the main ORANGE/terracotta brand accent colour
                (buttons, links on hover, highlights, the marquee strip)
   --terra-d  : a darker shade of terra, used for button hover states
   --sand     : light tan/gold accent, used on dark backgrounds (footer, hero)
   --taupe    : muted brown-grey, used for body/paragraph text
   --concrete : light grey, used for small labels & secondary text
   --border   : very light tan, used for card borders & dividers
   --white    : near-white, used for card backgrounds (slightly warmer than pure #fff)

   ⚠️ Do not rename these variables (--cream, --terra, etc) — they are
      used by name throughout this file and the other page CSS files.
      Only change the hex value AFTER the colon.
