/* Rovyn marketing site — editorial, serif-led, quiet.
   Serif is the editor's voice; the system sans is the app's.

   Colour comes from one place: assets/rovyn-logo.png. The ribbon's stops were
   sampled from the actual pixels; the page ground in dark mode is the tile's
   own indigo-navy. The ribbon is the single brand moment and is rationed —
   it is allowed on the mark itself, the nav's current/hover tick, the primary
   CTA's ring, the edition card's spine, and one blurred ambient wash behind
   the hero card. It never sits under text and never carries text: no single
   text colour clears AA across the whole ramp (white fails on the ember and
   cyan ends, ink fails on the violet), so anything legible sits on a solid. */
