/* KastorFlow site — one stylesheet for every page.
   Layout: one 1120px column on a light-neutral canvas; the hero pairs copy with a
   JetBrains Mono instrument panel (the product's signature); everything else is quiet.
   Visual language follows the extension (ADR-012: Linear, indigo #5e6ad2 as the only
   action colour, Inter for UI, JetBrains Mono for instrument moments only). */
