/* Phase 144 — Buchungskalender.
 *
 * Gleiche Strategie wie forms.css: Die Seiten stammen oft aus importierten Bundles mit
 * aggressiven Resets (Tailwind preflight, button { all: unset }), also tragen die
 * darstellungskritischen Eigenschaften !important. Wurzel ist .nexo-booking[data-nexo-island],
 * damit die Spezifität über einem nackten `button { … }` des Bundles liegt.
