/**
 * lesson-editor.css   (Wave 19, 2026-05-23)
 *
 * Styles for:
 *   • lesson-editor.js     — board-level lesson configuration modal
 *   • tile-quiz-editor.js  — per-tile quiz / timer / conditional
 *                            section embedded in the props panel
 *
 * A11y contract:
 *   - All inputs have visible labels (markup-side, not just placeholder).
 *   - Min tap targets 44×44px via :where() floor.
 *   - Error text is real text, not just color (announced by SRs).
