/* =========================================================================
   Starvest — starvest.co.uk
   Deep-space observatory shell.
   Near-black indigo void, faint twinkling CSS star-field, starlight off-white
   text, a luminous violet "guide star" accent. Display: Space Grotesk
   (techy geometric) over Inter (clean humanist sans). Premium telescope-shop
   polish. Per-brand accent injected from site.yaml (--accent), default below.
   Mobile-first.

   This shell is deliberately STRUCTURALLY distinct from the sibling FBM
   sites: no top utility band, a single centered-wordmark observatory header
   with the nav on a row beneath it, a top-down "dome" mobile sheet, and a
   stratified deep-space footer.
