/*
 * Qadah · Session player layout (Phase 5 → polished in Phase 10 Fix 7)
 *
 * UX rules:
 *   - Slide is the focus, fills the viewport.
 *   - Sara floats bottom-end as a small draggable tile.
 *   - Mic button is centered + primary; slide nav is secondary (smaller, ghost).
 *   - Transcript opens as a bottom drawer that PUSHES the slide up — never a modal.
 *   - Text input is hidden by default; one click toggles it as a strip above the bottom bar.
 *   - "Avatar offline" lives only INSIDE the Sara tile, never as a corner toast.
 *   - Phase 1.5 tokens — no blue, no gradients, no glassmorphism, no resting shadows
 *     (the only shadow lives inside an animation @keyframes).
