/* =====================================================================
   SCELTA — SITE STYLES · shared design system
   Homepage V1 (approved 2026-10-03) + supporting pages (Platform,
   Approach, Contact, Client access, Demonstrator shell).

   Near-black ground, warm off-white ink, Instrument Serif for display
   headlines only, a quiet system sans for everything else. The vehicle
   and the product carry the page; the interface recedes.

   Rules this file holds to (from the 2026-10-03 audit):
   - no customer-facing text below 12px; body text 16–17px
   - every text colour is --ink-4 (≈5.4:1 on --bg) or stronger
   - navigation never disappears: below 1100px it moves into a menu
   - motion is optional: everything respects prefers-reduced-motion

   Breakpoints (max-width): 1279 header CTA label shortens · 1099 nav → menu
   · 959 grids collapse to one column · 719 phone layout · 559 small phone.
   Phones held sideways: (orientation: landscape) and (max-height: 560px).
