/* ============================================================================
   AFTON SOLUTIONS — SITE.CSS  (single source of truth)
   ----------------------------------------------------------------------------
   This file owns every GLOBAL, cross-page style: tokens, the type scale,
   nav + mobile drawer, footer, buttons, and the CTA band. Every page links
   this file. Change a global here once and it changes everywhere.

   RULES (do not break these — see CLAUDE.md "Source of Truth Rules"):
   1. Global components (nav, footer, buttons, CTA, type scale, gutters) live
      ONLY here. Never redefine them inside a page's <style> block.
   2. A page's inline <style> may ONLY contain layout that is unique to that
      page (its hero, its bespoke sections). It must reuse the tokens below.
   3. Body text is ALWAYS 100% opacity. Use the --ink* color tokens, never
      rgba() with an alpha < 1 on readable text.
   4. Horizontal page padding is controlled by --gutter (flips to 10% on
      mobile automatically). Never hard-code section side padding or add
      per-page !important padding overrides.
   5. No arrows inside buttons or links. Ever.
   6. On mobile, Permanent Marker is swapped to Inter 700 globally (below) —
      never add per-page mobile font swaps.
