/* ============================================================
   AccentBuddy — The Bright Lab
   ============================================================

   A phonetic laboratory instrument on a clean, well-lit
   examination surface. Precise, clinical, unhurried.
   The human voice is the only warm thing that passes through.

   TWO TEMPERATURES
   Teal  — the instrument. Cool, clinical, always watching.
   Red   — the voice. Warm, human, alive.
   The entire UI tension lives between these two.

   FOUR VOICES
   Source Serif 4    — the specimen. Text being examined.
   Literata          — the verdict. Analysis in prose.
   Plus Jakarta Sans — the chrome. UI that stays quiet.
   JetBrains Mono    — the readout. The instrument speaks.
