   PURPOSE
   ───────
   De-duplicate chrome elements (reset · body baseline · beta strip ·
   header · floating language toggle · footer · focus + a11y universals)
   currently duplicated between main.css v3.6.0 and legal.css v2.0.0.
   Single source of truth for shared UI across all kidab.io public
   pages, with comprehensive device + accessibility adaptation.

   APPLICABILITY MATRIX (F-PRE-01 fix)
   ────────────────────────────────────
   §1 Reset                  → ALL pages
   §2 Body baseline          → ALL pages
   §3 Beta Strip             → Pages that include .beta-strip element
                                (currently: index.html · beta-terms.html)
                               INTERIOR pages MUST add their own
                                body padding-top:36px when strip present
   §4 Header + nav           → INTERIOR pages only
                                (privacy · terms · beta-terms · contact · help)
   §5 Floating lang-toggle   → HERO page only (index.html)
   §6 Footer                 → ALL pages (kebab-case markup)
   §7 Utility classes        → ALL pages
   §8 Focus + a11y universal → ALL pages
   §9 Print                  → ALL pages (auto-engages on print)
   §10 Reduced-data          → ALL pages (disables expensive blur)
   §11 Reduced-transparency  → ALL pages (opaque fallbacks)
   §12 Pointer/hover gate    → ALL pages (touch-vs-mouse divergence)
   §13 PWA standalone        → ALL pages (when installed as PWA)
   §14 Responsive ladder     → ALL pages

   DESIGN DECISIONS APPLIED
   ────────────────────────
   - D-COLOR-01: Light (Shell White #FFFFFF) is functional default;
                 dark via [data-theme="dark"] or
                 @media (prefers-color-scheme: dark)
   - D-TYPO-01:  UI chrome (nav, buttons) uses var(--font-system)
   - Rule 11.21: All values via canonical tokens from tokens.css v2.0.0
   - Rule 11.15: .woff2 only (declared in fonts.css v3.2.0)
   - WCAG 2.2 AA: touch targets ≥24px · :focus-visible ·
                  prefers-reduced-motion · forced-colors ·
                  non-text contrast 3:1 (§1.4.11)

   DEVICE COVERAGE
   ───────────────
   - Mobile portrait/landscape · tablet portrait/landscape · desktop
   - Foldable · notched (iPhone X+) · ultrawide
   - Touch · stylus · mouse · keyboard · D-pad (smart TV)
   - PWA standalone · browser · in-app browser
   - 1x · 2x · 3x display density
   - Light · dark · forced colors · high contrast preferences
   - Reduced motion · reduced data · reduced transparency preferences
