/* ── Bilingual: Devanagari line-height (extracted from a reviewed a11y.css
   v2.0 proposal, adapted to this file's real selectors — most of that
   proposal targeted classes/elements that don't exist in this app's actual
   Tailwind-driven markup and would have had no effect; this one rule was
   genuinely useful and standards-based). Devanagari conjuncts and matras
   (vowel marks above/below the base glyph) need more vertical room than
   Latin text at the same line-height, or they visually clip against the
   line above/below. Progressive enhancement: only applies where lang="hi"
   is actually set, costs nothing where it isn't. Does not set font-family
   here — that is already handled per-surface by each page's own font
   stack (dashboard.php, business.php, cards/id.php, cards/visiting.php,
   the numerology report), all of which already load Noto Sans Devanagari
   correctly as of this session's earlier fix. */
