// Left team panel (research 06 §11.1, research 09 §3.1): one row per seat — avatar (band icon once picked), name, LP
// tower, status glyph (… acting / ✓ ready / ⌛ deciding / ⚔ combat / door left / ✕ dead), AI badge, "you" marker, the
// field being watched (eye badge), and emote bubbles.
// Observing (client-side combat, `observe` prop — the official flow): tapping a teammate's avatar expands a mint
// "前往查看" button under the row (when that teammate can be observed now; otherwise the reason is toasted through
// onWatch); while observing, the own row shows a "返回战场" button. Without `observe` (server-run combat) a click
// watches that player's field at once.
