/* css/db.css — module M3: Base de datos, Cadenas, import dialog, OSM scan & review.
 * Builds on core tokens/components (css/core.css). Prefixes: .mt-db-*, .mt-chains-*, .mt-imp-*, .mt-osm-*.
 * Direction: the "analyst's workbench" of the shell — dense but calm data surfaces, tabular numerals,
 * crimson only for selection/primary actions, amber for "local, not yet saved" state.
