   ── CHANGING THE ACCENT COLOUR ─────────────────────────────────────────────
   Every accent, gradient and glow derives from --hue and --chroma below.
   Change --hue alone and light *and* dark mode follow, keeping their lightness
   relationship — which is exactly what breaks when hex values get swapped by
   hand.

       195  teal (current)     255  blue
       310  magenta-purple     145  green

   The plain hex values are the pre-2023 fallback (oklch landed in Firefox in
   May 2023). They are the teal set; if --hue changes and you still care about
   old browsers, update them too — or delete the fallback block when you don't.
