   EarthingSolutions.co.in — Main Stylesheet
   v6 — ROYAL GROUND (16-Jul-2026)

   Brief: "amazing with a wow factor, classy royal and elegant."
   Direction: heritage private-bank restraint on the v5 DEEP GROUND canvas.
   Near-black navy, champagne-gold hairlines and eyebrows, oversized
   Instrument Serif display type with italic flourishes, sharp edges
   (--radius stays 0). Gold is an ACCENT, never a fill; the industrial
   blue family keeps every interactive fill (white text on blue).

   Same architecture as v5: ONE :root token block, every colour below it
   is a var() token. All v5 selectors preserved — this is a reskin, not a
   rename. NOTE: --amber-t remains reserved for the IS 3043 / MTC
   compliance badge ONLY; the new champagne gold is a separate family.

   Brand spine: 05090F blue-black, 0F1B2A near-navy, 12467F industrial
   blue, C9A44C champagne gold.

   Contrast (WCAG, computed — not eyeballed):
     ink        E9F1FA on bg-0 05090F ..... 17.6:1
     ink-muted  A9BACC on bg-0 ............. 10.1:1  (8.7:1 on bg-1)
     ink-faint  7C90A5 on bg-0 ............. 6.1:1   (5.3:1 on bg-1)
     copper     4E96E4 on bg-0 ............. 6.5:1   (5.6:1 on bg-1)
     gold       C9A44C on bg-0 ............. 8.4:1   (7.3:1 on bg-1)
     gold-2     E4C57E on bg-0 ............. 12.0:1  (10.4:1 on bg-1)
     gold-3     8A6D2F ..................... decorative strokes only, never text
     amber-t    E8B75C on amber-bg/bg-1 .... 7.8:1
     white      on blue  12467F ............ 9.5:1

   CINEMA HOMEPAGE (17-Jul-2026)
   The scroll-cinema homepage experience, ported from the approved prototype.
   EVERY selector below is namespaced under body.home-cinema (set on the
   homepage <body> only) so inner pages are untouched. Like /projects/, the
   homepage is a deliberate dark chapter: the dark-ramp tokens are re-scoped
   on body.home-cinema — header, kept sections (Our Range, FAQ) and chips
   restyle themselves through the same tokens they already read.
   JS states are gated under html.js (set by main.js/cinema.js) and cleared
   by html.cine-reduced, so no-JS and reduced-motion render final states.
