/* Dhristi landing page. Light palette with dark type for contrast; no dark surfaces.
   Palette (design playbook, colour system): 4 colours, 60/30/10.
     60  neutrals: paper and white grounds (warm off-white, complementary to cobalt)
     30  ink for type, and the pale cobalt tint for alternate bands
     10  cobalt, the ONE accent: calls to action, links, focus, and the one must-notice line
   Flame was retired on 29 September 2026: a second accent competed with the CTA for
   attention on every section. Emphasis inside a colour comes from ink tiers (ink, ink-2,
   ink-3), not from more hues.
   Type: Anton for display headings, Open Sans for subheadings and UI labels,
   Glacial Indifference for paragraphs. All self-hosted, SIL OFL (assets/fonts/OFL.txt). */
