   Hailcat.app · Seraph design system (matches app v1.51+)
   The site-wide re-skin for the Seraph rebrand. Same class API as
   the retired mint.css so pages swap with one stylesheet line.
   Tokens mirror the app's SeraphSkySkin.swift / SeraphTheme.swift:
   cool-neutral ink on white, ONE vertical pale-sky-to-white ground,
   gold as a luminous accent, azure for anything read at small
   sizes, frosted white glass. Committed light: no dark palette,
   matching the app's one-appearance rule. Type stays Hanken
   Grotesk (the planner app's face).
