## Summary
Closes#34.
- Upcoming and Past calendar tabs show a short message when that list is empty, so a calendar with no events is no longer a blank content area.
- Empty copy stays hidden on a tab that has events.
## Test plan
- [ ] Open `/calendar` with no `CalendarEvent` rows and confirm Upcoming says “There are no upcoming events to display.”
- [ ] Switch to Past and confirm it says “There are no past events to display.”
- [ ] Add an upcoming event and confirm the Upcoming message is gone while Past still shows its empty message if there are no past events.
- [ ] `uv run python manage.py test schasite.tests.PublicPageTests.test_calendar_shows_empty_state_when_no_events schasite.tests.CalendarEventTests.test_calendar_page_splits_past_and_future`

## Summary
Closes#32.
- Keep an event on Upcoming until its end date is over. If `end_time` is set, it drops off once that time passes on the end date, so an in-progress multi-day event stays visible.
- Render the Past tab from `past_events` instead of `future_events`.
- Show the start–end date range when the dates differ.
## Test plan
- [ ] Multi-day event that started yesterday and ends tomorrow appears under Upcoming
- [ ] Event whose end time has already passed appears under Past
- [ ] Future single-day event still appears under Upcoming
- [ ] Past tab lists finished events only
- [ ] `uv run python manage.py test schasite.tests.CalendarEventTests`

## Summary
Closes#30.
- Green check (“Paid this year”) on membership list, person list, and person inline when `Payments.email` matches `MembershipPerson.email` (case-insensitive) for the current calendar year. Also matches via the payment’s person FK.
- CSV downloads for payments, memberships by person, and memberships by address prompt for a year (default current year, or All years). Payments filter by payment date; memberships filter by record created year. Changelists also get a year sidebar filter.
- Payments admin remains searchable by email.
## Test plan
- [ ] `uv run python manage.py test`
- [ ] In admin, open Memberships / Membership people and confirm a green check when a same-year payment email matches, and a red X otherwise
- [ ] Select memberships → Download CSV by member/address → pick a year → confirm only that year is in the file
- [ ] Select payments → Download payments CSV → pick a year → confirm filter
- [ ] On Payments, search by email and filter by year

## Summary
Closes#28.
- Add optional `start_time` / `end_time` (`TimeField`) on `CalendarEvent`
- Expose times in Django admin list + form
- Replace hardcoded calendar template times with `time_range_display`
- Add migration `0013` and unit coverage for time formatting
## Test plan
- [ ] `python manage.py migrate`
- [ ] `python manage.py test schasite.tests.CalendarEventTests`
- [ ] In admin, edit an event with start/end times and confirm calendar page shows them
- [ ] Confirm events without times hide the Time rowReviewed-on: #29
## Summary
Closes#18.
- Add per-page titles, meta descriptions, Open Graph/Twitter tags, and canonical URLs on public `base2.html` pages
- Improve semantic structure: skip link, primary nav ARIA, single `<main id="main-content">`, heading hierarchy, descriptive image alts
- Publish `/robots.txt`, `/sitemap.xml`, and `/llms.txt` (linked from site head via `rel="alternate"`)
- Agentic/a11y fixes: membership checkbox label associations, ZIP `name` attribute, layout stability (image aspect-ratio / min-height), footer year without `document.write`
- WebMCP deferred — membership + Stripe checkout remain standard HTML/Stripe flows; no audit flag justified custom MCP surface yet
## Lighthouse / agentic notes
Baseline Lighthouse runs still need Chrome Canary export on staging/prod. Structural SEO/a11y items from the ticket are implemented so follow-up audits can capture before/after scores.
Expected audit wins vs prior minimal `charset`+`viewport` head:
- SEO: unique titles/descriptions, crawl directives, sitemap
- Agentic/a11y: landmarks, labels, CLS-oriented image sizing
## Test plan
- [x] `uv run python manage.py test schasite` (34 passed)
- [ ] Spot-check Home/About/Calendar/Dues/Membership/Board/Links in browser
- [ ] Confirm `/robots.txt`, `/sitemap.xml`, `/llms.txt` on deployed host
- [ ] Run Lighthouse SEO + Agentic browsing on key pages and note before/after pass ratio on the issue
