/**
 * navigation.css — Meadow Lane Park
 * Primary navigation, mobile menu, and member login CTA.
 *
 * Key fixes vs. original:
 *  - .layout-header z-index raised to 110 (above page, below Drupal toolbar 501).
 *  - Mobile menu uses position:fixed with z-index 499 (clears content, under toolbar).
 *  - Removed !important overrides; specificity handled via selector chain.
 *  - Drupal menu block renders its own <ul> inside the region — defensive reset added.
 *  - isolation:isolate on header prevents stacking context bleed from children.
