   EYE-COMFORT DESIGN (long-read safe)
   ----------------------------------------------------------------------------
   Design principles for hours of comfortable reading:
     1. Warm off-white canvas (never pure #ffffff) — reduces glare
     2. Warm dark text (never pure black) — reduces harsh contrast
     3. Contrast ~8–10:1, not 21:1 — restful but still very readable
     4. Amber / honey accents instead of blue-violet — no blue-light strain
     5. Larger body text (17px), longer line-height (1.85) — easier tracking
     6. Warm-toned reading highlight — visible but never glaring
     7. Soft shadows, no harsh edges, muted hover transitions
     8. Optional warm-night mode via prefers-color-scheme

   EMOJI-SAFE (this revision)
   ----------------------------------------------------------------------------
     · No gradient-text clipping anywhere — every heading uses a solid fill
     · Full color-emoji font stack appended to every text font-family
     · font-feature-settings stripped from headings (preserves flag ligatures)
     · Result: 🇬🇧 🌍 📖 🌱 and every emoji renders in full native color
