   Langue Lab — Stylesheet
   
   DESIGN DIRECTION: Editorial / refined — inspired by quality print design.
   
   FONTS:
     - Playfair Display (serif display) — for headlines, giving the app a 
       cultured, literary quality appropriate for language learning
     - IBM Plex Mono — for the target phrases (monospaced makes each character
       distinct, helping with careful pronunciation reading)
     - IBM Plex Sans — clean, neutral body text
   
   COLOURS:
     --ink:    near-black for primary text
     --cream:  warm off-white background (less harsh than pure white)
     --gold:   warm accent for active states and highlights
     --french: muted indigo-blue (evokes France)
     --arabic: warm terracotta (evokes MENA)
     --good:   muted green for high scores
     --ok:     amber for middling scores
     --low:    muted red for low scores
