/* ================================================================
   RAINBOW NATION LANGUAGE PICKER  —  v2 (rattle-fixed + compact)
   ----------------------------------------------------------------
   CHANGE LOG
   • RATTLE FIX
       Previous build: the "Did You Know" fact card grew/shrank with
       each language's text length. Hovering Zulu (long) → Xhosa
       (shorter) pushed the grid up, the cell under the cursor changed,
       mouseenter re-fired on a different cell, height changed again,
       repeat → visible rattle.
       Fix: .rn-fact-text is now hard-clamped to a fixed 4-line box
       with -webkit-line-clamp (or min-height fallback). Height never
       changes between renders → grid never shifts → no rattle.
       The pop animation also dropped its transform:scale (which was
       moving the card by sub-pixels and adding to the jitter); it is
       now a pure opacity cross-fade.
   • COMPACT HEADER
       "Izilimi / Languages" title and "South Africa's 11 Official
       Languages" subline merged into a single row separated by a dot
       — saves a row of vertical space.
   • COMPACT LANGUAGE CARDS
       The redundant native sub-label was removed from every card
       (Zulu/Xhosa/Tswana etc.). Cards are now single-line, tighter
       padding, denser grid. The native name still appears in the
       fact card when that language is hovered, so the information
       isn't lost — just not duplicated 11 times.
