Fix: remove unused 'accessibleMonths' variable (tsc exit code 2)
Features:
- AllYearsLetter view: all years in chronological order, reachable
from "All Years" at the top of the sidebar
- PDF export: window.print() with @media print CSS — sidebar, toolbar,
and chrome hidden; each year starts on a new page via page-break
- "Download all" exports a plain-text file of every year's letter
- ntfy notifier: standalone Node.js service (notifier/) that fires a
push notification via ntfy on the 1st of each month; configurable
via NTFY_TOPIC, NTFY_URL, CRON_SCHEDULE, APP_URL env vars
- docker-compose: adds `notifier` service alongside `app`; reads from
.env (example in .env.example); NTFY_TEST_ON_START=true sends a
test ping on container start
