/*
 * HD Door Designer — Designer 3
 * ------------------------------------------------------------------
 * Scoped under .hd-d3 (inside .hd-dd, so the classic tokens + box-sizing reset apply).
 * Mobile-first. Below 720px: the door on top, a strip of tabs under it, and a dock fixed to
 * the bottom of the view holding the options sheet and the save box. From 720px: the door on
 * the left, the toolbox column on the right with the save box always in view.
 *
 * Sections
 *   1. Shell, header, titles
 *   2. Type and style cards
 *   3. Door stage and dots
 *   4. Toolbox (rows, tabs, sections, tiles)
 *   5. Dock: sheet, nudge, save
 *   6. Wider screens
 *   7. Motion (+ reduced motion)
 *   8. After saving: lights, quote, call back
