/* ---------------------------------------------------------------------------
 * panels.css — THE ONE DRAWER (SPEC §16).
 *
 * There is exactly ONE panel element: #drawer. Storms, storm detail, layers,
 * home, and settings are VIEWS INSIDE IT. It is glass, translucent, globe
 * visible behind, never full-screen. Docking adapts to WIDTH, not device —
 * the same DOM element becomes a bottom sheet when narrow and a left rail
 * when wide. No isMobile, no second markup tree.
 *
 * The drawer slides ONCE. Moving between views does not re-animate it; only
 * the view body crossfades. Four sibling panels alternating open/closed read
 * as a stack of drawers fighting each other, which is what this replaced.
 *
 * All values are custom properties written from tokens.js at boot; the
 * literals in :root of index.html are first-paint fallbacks only.
 *
 * Motion: transform and opacity ONLY (SPEC §9). The sheet slides with
 * translateY, the rail with translateX. Nothing here animates height.
 * ------------------------------------------------------------------------- */

/* A CLOSED PANEL IS OFF-SCREEN, NOT GONE.
 *
 * The open/close animation is transform + opacity only (the §9 rule), so a
 * closed panel is still laid out, still in the DOM, and — the bug — still
 * FOCUSABLE. Tab walked through invisible storm rows.
 *
 * `display: none` would fix focus but kills the slide. `visibility: hidden` is
 * the right tool: it removes the element from the tab order AND from the
 * accessibility tree, but unlike display it is animatable, so the slide-out
 * still plays. The delayed transition is what makes that work — visibility
 * flips to hidden only AFTER the transform finishes, so the panel is still
 * visible while it slides away, then goes untabbable on arrival. Opening is
 * instant (0s delay) so it's focusable the moment it starts moving.
 *
 * `inert` would also work but is not animatable and would need JS to toggle;
 * this keeps the whole open/closed contract in CSS where the animation lives. */
