   Kareva: site header

   Two states, switched by header.js:
   - default      full-width bar: wordmark left, menu centred, button right
   - .is-compact  centred floating pill with the small brand mark
   The move between them is animated with GSAP Flip (positions and sizes),
   while colours, the glass and the logo swap use the CSS transitions below.

   Colours follow body.header-light (set per section by home.js / site.js):
   light text over dark sections, dark text over light ones.
