/* ============================================================
   L'CLAIRE JEWELLERY — "CUT IN LIGHT"
   One design language for the whole site.

   Two surfaces, like a jeweller's counter:
     velvet — the tray a stone is shown on (night, ivory type)
     paper  — the card that comes with it (ivory, ink type)
   Components read --fg / --accent from whichever surface holds them.
