/* ==================== FIT GUARD (desktop + tablet) ====================
   The invitation modal title and the cover pre-text use white-space:nowrap
   inside fixed ~410px cards. The earlier rules let them grow to 29-42px,
   which overflows the card and gets clipped (phones stay small so mobile
   looked fine). Cap them at measured one-line sizes so nothing is cut off.
   These high-specificity rules come last, so they win over the tablet/
   mobile/height-aware blocks above, which are left untouched.
   - Khmer title "សូមគោរពអញ្ជើញ" fits at 26px = 300px < 310px box
     (clips at 29-42px), so cap it on all non-phone widths (>=481px).
   - English title "You Are Invited" fits at every existing size, so it is
     left unchanged.
   - English pre-text "WE ARE GETTING MARRIED" fits at 15px + 5px tracking =
     257px < 274px box (the tightest desktop box, at 851-900h where cover
     width shrinks to 370px). Clips at the 22px + 8px base (450px) on tall
     desktops and at 15px + 4px (275px) on the 274px box. */
