/* ─── Iteration log ─────────────────────────────────────────
   v3 (2026-03-10):
   - gap 0.6rem → 0.25rem  (lockup felt like two separate elements)
   - line-height 1 → 0.82  (Cormorant 'y' descender too aggressive at lh 1)

   v4 (2026-03-10): precise x-height alignment (first attempt, rem-based, imprecise)

   v5 (2026-03-10): x-height alignment using em units — scales with font-size
     METHOD: align-items: flex-start (top-anchor) + margin-top on wordmark
     CORMORANT GARAMOND hhea metrics:
       ascender        =  0.904 × font-size above baseline
       descender       =  0.220 × font-size below baseline
       natural lh      =  1.124 × font-size
       half-leading    = (0.820 − 1.124) / 2 = −0.152em
       line-box top    =  ascender + half-leading = 0.904 − 0.152 = 0.752em above baseline
       x-height        ≈  0.420em above baseline
       x-height from line-box top = 0.752 − 0.420 = 0.332em
     CALCULATION:
       S height        =  1.4em (= 2 × cap-height, keeps cap-tops at S midpoint)
       S centre        =  0.700em from S top
       margin-top      =  0.700 − 0.332 = 0.368em → 0.37em
     CONSTRAINTS MET:
       x-height top    = S top + 0.37em + 0.332em = 0.702em ≈ S centre ✓
       descender bottom= 0.37 + 0.752 + 0.220 = 1.342em = 118px < S height 123px ✓
