- api.js: add exponential backoff retry (3 attempts, 500/1000/2000ms) for
GET requests on network errors and 5xx responses; mutating methods are
not retried since they are not idempotent
- api.js: add offline indicator — fixed pill banner appears at bottom of
page when navigator goes offline, disappears when back online
- style.css: add styles for offline banner and session expiry warning
- auth.js: show amber warning banner below nav when session expires within
24 hours (with exact hours remaining); dismissible with X button
- auth.js: fix password min-length client-side check from 6 to 10 to
match the backend
- log.js, flock.js, budget.js: disable submit button during async request
and re-enable in finally block to prevent double-submits and make loading
state visible
- dashboard.js: fix chart date labels to use user's configured timezone
instead of the browser's local timezone
