/**
 * lesson-slp.css   (Phase 3.4 — Batch C / D4.A, 2026-05-24)
 *
 * Styles for:
 *   • js/builder/lesson-editor-slp.js  — author surface (modal +
 *                                         step rows + topbar pill)
 *   • js/runtime/use-lesson-slp.js     — learner surface (per-step
 *                                         prompt + Listen/Next/Skip)
 *
 * Namespace: .lpslp-*  (LessonPlan-SLP — kept distinct from
 * lesson-editor.css's .lesson-* namespace so the two editors can
 * coexist on the same page without rule bleed).
 *
 * A11y contract:
 *   - Buttons hit the 44×44 tap-target floor.
 *   - Inputs stay at 16px so iOS Safari does not zoom on focus.
 *   - Prompt text scales with prefers-larger-text via REM.
