/* ── Italic clipping fix (site-wide) ─────────────────────────
   Italic glyphs (y, g, j, f, k) have right-leaning swashes that
   extend past the geometric character box. Combined with
   -webkit-background-clip: text and/or body { overflow-x: hidden },
   the swash gets clipped. Solution: turn the em into an
   inline-block with padding so the box itself includes the swash.
   Applies to every display heading variant on the site.
