Lead the dropdown with subscriptions: a dedicated card shows the binding
window as the hero (gauge, remaining %, reset countdown, and a burn-rate
'left at this pace' line), a secondary window, and the Opus/Sonnet split for
Max, with a stale marker for older Codex data. Demote spend/usage to a compact
strip and surface cross-tool headroom. Add pure burn-rate / time-to-exhaustion
and binding-window math in Core. Kill the menu scroll indicator for real
(NSScrollView hider) so content stays aligned. Spend-cap alerts default off
(pay-per-use, opt-in).
