/**
 * door-wander.css — Door A: Wander (the Walkable Map), /wander/.
 * task-038 Phase 2, productionised from the task-034 concept-A mock.
 *
 * Token discipline (docs/design-system/palette.md): every colour below is a
 * --ui-*/--color-* custom property defined in layouts/_default/baseof.html —
 * zero raw palette hex, so light + dark ride the token swap for free. The
 * only local custom properties are page-scoped scalars and the subtree tint
 * indirection (--dw-tint), which always resolves to a chart-ramp token.
 *
 * Chamfer grammar (docs/specs/design-system-chamfer.md): containers wear the
 * four-corner cut, interactive affordances the two-corner cut — both consumed
 * from the baseof tokens.
