/* ============================================ the 2D redesign's fallout ===
 * v1.6.0 rebuilt the 2D page around "the table is the interface": the stage
 * became a single column, both rails moved behind a hamburger, and the base
 * `.stage` (three columns) and `.panel` (scrolling flex column) rules were
 * DELETED from pool.css.
 *
 * This page still uses that layout. It shares pool.css, so deleting those
 * rules collapsed its canvas wrapper to zero height — and app3d's resize()
 * bails below 40px, so the WebGL backing store stayed at the HTML default
 * 300x150 while CSS stretched it to 1424 wide. Five rendered checks failed
 * (black canvas, no shading, no cloth, no red ball) on a page whose markup
 * and JavaScript were untouched and perfectly valid.
 *
 * The 3D table keeps the reading-room layout deliberately: it has no dock to
 * float, its canvas is absolutely positioned inside .table-wrap-3d, and the
 * camera bar already occupies the space a dock would want. So the rules are
 * restored here, scoped to body.is-3d, in the stylesheet only this page loads.
 *
 * ⚠ pool.css is SHARED. Anything removed from it must be checked against
 * /pool/3d/ before it ships, exactly like the shared engine modules. */
