/* ================================================================
 * VIETSPEECH — SHARED FORM STYLES
 * ----------------------------------------------------------------
 * File CSS dùng chung cho mọi biểu mẫu đánh giá (B3B, VLA, ICS,
 * SPAA-C, ASD-P1, OralMotor...). Mọi class/biến đều có thể cấu hình
 * trong FORMS.md (PHẦN 1).
 *
 * Cách dùng:
 *   <link rel="stylesheet" href="/css/forms/forms.css">
 *
 * Inline CSS riêng từng form CHỈ nên dùng cho phần đặc thù (ví dụ:
 * emoji icon ở SPAA-C, mouth drawing ở OralMotor).
