Tied off #start's inline display attribute (which the engine flips
to 'none' the moment a match begins and back to 'flex' on every
return path), so we don't need a parallel body class to maintain.
Initial state (no style attribute) also matches `:not(none)`, so
the HUD is hidden on first boot before any JS runs.
Second selector: while the World Tour career UI (#wt-root.show)
is open, #start is forced to display:none so the first selector
no longer applies — the empty match HUD would otherwise leak
through the career screens. :has() pulls the body up when a
`.show` World Tour root exists and hides #hud unconditionally. */
