/**
 * widget.css — общий CSS для всех форм и селектора приложения «Результат задачи».
 *
 * Раздаётся через API Gateway по роуту /widget.css.
 * Подключается в формах через <link> с $config['css_url'].
 *
 * Контракт: docs/form-contract.md (v1.2)
 *
 * Правила:
 *   - Общие стили (дублируются в 2+ формах) — здесь.
 *   - Уникальные стили (1 форма) — в форме, в отдельном <style>.
 *   - Уникальные цвета (subtask — оранжевые кнопки) — через CSS-переменные.
 *
 * Версионирование: ?v=N в config['css_url'] (bump при обновлении).
