/* ============================================================================
   stevenaholland.com — Steven's 2020 "Sandpaper Melon" design, modernized.
   Deep-purple page with a fixed sidebar card, a white content sheet with a purple
   sawtooth right edge, Poppins, "# Heading #" accents, a grey + lavender display
   headline and a sparing yellow accent. Colours derive from the profile's
   --bs-primary (card purple) and --accent (yellow), so the editor recolours live.
   Loaded after site.css (via _ThemeHead), so these rules win.
   ============================================================================ */
