A val that watches every showtime of The Odyssey at AMC Lincoln Square 13 & IMAX for the next 3 weeks (sliding from now), renders a live gallery of clickable calendar buttons (date · time · format · seats occupied vs capacity), and emails an update digest every 25 minutes.

• GET / — the gallery. Each showtime is a button; click it to go straight to the AMC seat map / ticket page for that showing. Day buttons jump to each date.
• GET /api/data.json — the raw report (showtimes grouped by date).
• GET /source — this repo.

Source	What you get	Requires
AMC Theatres API (primary)	Exact dates, times, formats, auditoriums, sold-out flags and precise occupied/total seat counts (via seating-layouts)	AMC_VENDOR_KEY
Fandango napi (fallback)	Dates, times, formats, availability and buy links — no seat counts	nothing (auto)

The AMC website itself (amctheatres.com) and its api.amctheatres.com showtimes endpoint are behind a bot-protection queue and vendor auth, so the app favors the official developer API and falls back to Fandango's internal API (the same source other public showtime scrapers use).

1. Get a free AMC developer key (self-serve, free): https://developers.amctheatres.com Note: keys are reported to activate on Thursdays — if yours isn't live immediately, the app keeps working on the Fandango fallback until it is.

2. Add the key to this val:

   👉 Add AMC_VENDOR_KEY here: https://www.val.town/x/cwervo/amc-odyssey-seats/environment-variables?key=AMC_VENDOR_KEY

Optional env vars:

• EMAIL_TO — digest recipient (defaults to cwervooo@yahoo.com). ⚠️ On the free Val Town plan, std/email can only send to your own Val Town account email. The digest tries EMAIL_TO first and, if that's rejected, falls back to the account owner's address so updates still arrive until you're on Pro.
• FANDANGO_THEATER_ID — override the fallback theatre (default AABQI = AMC Lincoln Square 13).

digest.ts runs on an interval. The free tier allows ≥ 15 minutes between runs; this val is configured for every 25 minutes. Each run:

1. Fetches all Odyssey showtimes at the theatre (next 21 days).
2. Pulls exact seat layouts per showtime (cached ~15 min in blob storage to be nice to the API).
3. Emails the digest and the gallery reflects the newest data on next load.

The referenced page (https://www.amctheatres.com/movies/the-odyssey-76238/showtimes) sits behind AMC's "Global Safety Net" bot queue (a JS-challenge redirect), so a serverless fetch can't read it, and the JSON API behind it rejects requests without a vendor key. This val uses the two working public paths instead — the official developer API (which returns the same data, plus seat counts) and Fandango.
