/*
 * Branch Locator — App Proxy page stylesheet (Story L.2)
 *
 * Token-driven styling for the public Filialfinder fragment served at the
 * generalized App Proxy root (/apps/filialen). Mirrors the `--bp-*` token chain
 * from branch-pickup-proxy.css so the locator inherits the merchant's Shopify
 * theme tokens (Dawn / OS-2.0) with neutral fallbacks. Scoped under
 * #branch-locator-app so it never collides with the pickup fragment.
 *
 * Companion: public/css/branch-pickup-proxy.css (Epic 18 pickup flow).
