DL-246
CoachTip resolves its chord ONLY via shortcutFor(id, platform) (DL-234’s single-derivation rule — never a hand-authored string) and renders it sequence-aware: a plus-chord (Ctrl+B) through ShortcutChip (which splits on "+", ShortcutChip.tsx:17), a RIG-2484 sequence ("G then B", no "+") as plain text so it does not render one giant <kbd>. Because it only reads shortcutFor’s return, it shows today’s Mod+B now and G then B automatically once RIG-2484 (PR #544) lands — forward-compatible, never blocked on it. Teaching ShortcutChip to split on " then " is deferred to the RIG-2484 impl. A parallel tooltip-local chord formatter was rejected (forks the single derivation this net exists to keep).
