/* ============================================================
   EM Snow topbar — split out of em.css (V1c, 2026-09-17)
   The .em-topbar header em-shell.js injects, its search/location controls,
   and their <=720px mobile rules. Moved here VERBATIM so the resort page
   (public/resortinfo.html) can style the ONE shell header WITHOUT loading
   the whole em.css (em.css restyles *, html, body and redefines --line, which
   would clobber the resort page's own base styles). Needs em-tokens.css for
   the --scrim / --line / --ink-* / --s* / --r* / --font-* tokens it consumes.
   Every em.css consumer also loads this file (immediately before em.css); on
   those pages it is identical CSS to what used to live in em.css.

  /* mobile menu: burger reveals the hidden page links as a dropdown.
     Only .open gets the absolute panel treatment - the closed state is untouched (still
     a normal inline row with the theme button always visible), so nothing that already
     lived in .em-nav-links (theme toggle etc) loses visibility by default.
     Review fix (2026-07-27): NOTE this .open ruleset styles the WHOLE .em-nav-links
     wrapper (no selector-level scoping) - the guard is DOM POSITION, the mirror of the
     .fl-nav-links fix in em-resort-skin.css. Any control that must stay put whether the menu is open or
     closed (e.g. resortinfo's Story/Stats toggle) belongs OUTSIDE .em-nav-links, as a
     sibling in .em-nav - never nested inside it, or it gets swept into the dropdown. */
