/* ==========================================================================
   Zion Care — mobile navigation
   Vanilla CSS. Scoped below the 64rem hamburger breakpoint; desktop untouched.

   The choreography, in order:
     1. Hamburger presses → fills charcoal, a gold conic ring sweeps once.
     2. The panel is revealed by a clip-path circle that grows *from the
        button itself* (origin fed in by nav.js as --zm-x / --zm-y).
     3. Page beneath recedes (scale + blur) behind frosted glass.
     4. Links rise in, one at a time, each un-blurring as it lands; the
        hairline under each draws left → right just behind it.
     5. The dock (CTA / call / email) slides up last.
   Closing plays the same in ~half the time with no stagger.
