/* =========================================================================
   QUALITY NOTE — Pronunciation Row Styling
   Added after the full "In your languages" data audit (see app.js header comment).
   The visual treatment below (slightly smaller + italic + letter-spacing on .phonetic)
   makes it immediately obvious to users that Row 2 is a pronunciation guide,
   not a repeat of the word in Row 1. This supports the strict two-row rule
   enforced in the JavaScript data layer.
   No other CSS changes were required.
