/* marketing.css — Celestium public marketing chrome.
   =============================================================================
   Layers on celestium-brand.css (the canonical token + font layer, shared with
   /dash and the /r render pages). This file is ONLY the marketing site skin:
   nav header, hero, pillar/why cards, prose, footer. Illuminated-almanac look —
   navy ground + gold-leaf, Fraunces display / Spectral text — matched to the
   iOS app's CosmicTheme.swift. No framework; hand-authored static pages.
