    /* ── TAB BAR ──
       The big primary switcher: an icon above a label, equal-width columns, a hairline card around
       the set, and a green rule under the active one. Built once here rather than on the Athletes
       page so the next surface that needs it inherits the behaviour instead of re-deriving it.

       Distinct from .seg on purpose. .seg is a small pill group for a secondary choice inside a
       page (sort order, leaderboard mode); .tabbar is the primary navigation of a whole workspace
       and is deliberately large enough to be the first thing the eye lands on after the title.
