/* =========================================================================
   K24 Sticky Header — Phase 2
   Compressed-state styling that activates when the legacy scroll handler
   in `assets/js/main.js` adds `.sticky-bar` to `.header-bottom.header-sticky`.
   No new JS required; this only refines the visuals of the existing system.
