/* =============================================================================
   MyApollo v3 — Unified nav.
   Shared by every v3 page (home, iainroberts, account, future pages).
   Mounted by shared/v3-nav.js into <div id="v3-nav-mount"></div>.

   Layout:
     • Logo (always)
     • Desktop ≥768px: full link row + theme + auth chip
     • Mobile/tablet <768px: hamburger + theme + auth chip (compact)
     • Auth chip: Google-G "Sign in" when signed-out, profile-photo circle
       when signed-in. On mobile/tablet the chip is photo-only (no text).

   Depends on v3-tokens.css + v3-components.css.
