/* Formalizer UI — RTL Persian, Vazir font.
   Theme: coffee brown (قهوه‌ای) — chosen to stand apart from the sibling
   apps (summarizer blue, OCR violet, transcriber crimson); deliberately not
   blue/teal/violet/crimson/green/orange.
   Layering follows the family's legacy "grid → white card" look:
   body #795548 · grid #d7ccc8 + border #a1887f · output #efebe9
   primary button #795548/#a1887f · cancel button #eec17a/#e6af08/#79522c · accent #a1662f */
