/**
 * courses/public/css/widgets.css
 *
 * Styles for interactive lesson widgets. Every selector is prefixed
 * `.tow-w-*` (TinyOffice-Widget) so widget styles never accidentally
 * collide with lesson-body prose styles. Widgets render inside the
 * lesson body, not as full-page chrome — so they need to feel
 * embedded, not bolted on.
 *
 * Visual language: matches the existing course look — light cream
 * background (#fafaf9 ish), zinc text, teal (#5a8c8c) accent, serif
 * Playfair for headlines, Inter for body, JetBrains Mono for technical
 * labels.
 *
 * Per-widget sections are separated with =========== banners so each
 * one can be edited independently. Shared primitives (frame, eyebrow,
 * pane, error) live at the top.
 */
