/* landing.css v8.18.1 | Buktika | SDL-PIL-14 Archetype B
   Depends: global.css v3.14.0, themes.css v2.4.0
   v8.18.1 (2026-06-30): Reworked the How It Works section into a balanced
             two-card narrative grid. Corrected the undefined governed-strip
             surface token, tightened spacing, and clarified Tika hierarchy.
   v8.18.0 (2026-06-30): Site-wide readability audit. Restored face-card,
             door-card, and governed-strip substantive copy to the 1rem body
             floor. Narrative selectors now exclude compact role labels.
   v8.17.0 (2026-06-30): Added the homepage Tika Standard governed-by strip.
   v8.16.0 (2026-06-13): MamaDEX and social upliftment identity aligned to
             Colour Map v3.15.0. Borders, labels, CTAs, and shadow tint now
             use mama-violet instead of the retired mama-earth brown.
   v8.15.0 (2026-03-13): Trilogy strip migrated to global.css v3.14.0.
             Removed: .sdx-trilogy-strip, .trilogy-chapter, :hover/:focus,
             .active, .trilogy-thumb (base), .trilogy-caption, .trilogy-num,
             .trilogy-label, @media 768px trilogy rules, @media 640px trilogy rules.
             Retained: .trilogy-thumb-[slug] background-image only.
             UX fix: inactive panels now full opacity (global.css).
   v8.14.0 (2026-03-10): OVR-6 — Film strip divider. Owner override. BKT-DOC-www-C Rule 8.
            Full-bleed 35mm film strip between .hero-wrap and .landing-fence.
            Pure CSS + inline SVG. No image assets. Centre panel shows "end of roll"
            warm-toned exposure. Partial frames bleed off both viewport edges.
            Film metadata text (emulsion, exposure data) in strip margins.
            Sprocket holes via SVG pattern. Grain via CSS noise filter.
   v8.13.0: Five owner-directed overrides (OVR-1 through OVR-5).
   v8.12.0: FIX-L (trilogy canonical HTML/CSS), FIX-M (breadcrumb — reversed by OVR-5).
   v8.11.0: FIX-H/I/J/K. v8.9.0: Six owner-directed fixes. v8.8.0: Five fixes. */
