/* legacy.css — THE BRIDGE. Delete this file, rule by rule, as phase 2 rebuilds
 * each page on the system in css/README.md.
 *
 * On 2026-09-25 the four retired sheets (style.css, views.css, surfaces.css,
 * header-search.css) were deleted. The group, person, compare, about and
 * feedback views had not been rebuilt yet and still emit their old class names
 * (.leaf, .detail-head, .room-card, .sheet-row, .compare-*, .fb-*, charts…).
 * This file is those sheets' rules for THOSE classes only — machine-extracted:
 * a selector survived only if it names at least one class that a live view
 * still emits and that the new system does not define, so nothing here can
 * restyle a new-system component (.btn, .chip, .table, .avatar, .seg, .fig …).
 *
 * The old sheets spoke a different token vocabulary. Rather than rewrite 1,700
 * lines, the old names are ALIASED onto the new tokens below, so both themes
 * and every colour decision come from tokens.css and nothing here forks the
 * palette. When the last rule that reads an alias is gone, delete the alias.
 *
 * Rule for phase 2: never ADD to this file. Rebuild the view on the system and
 * delete its section here in the same change.
