- Settings/General: Daily budget row (Off / USD amount / Tokens),
positive-finite validation, warns at 80% and alerts at 100%
- app-wide one-line banner above every section: --warn at 80%+, --bad
at 100%+, dismissible for the rest of the day
- USD caps compare raw USD against per-provider daily cost (works under
any filter); token caps evaluate only on the all-providers view since
provider-filtered history zeroes token fields (comparing against a
false zero would always pass)
212/212, build green.
