2   WIX HEADLESS BACKEND
3   ----------------------------------------------------------------------------
4   Reads tour dates, releases and videos out of Wix CMS collections so Dexter
5   can edit them in the Wix dashboard instead of editing this repo.
6
7   Design rule: the site NEVER waits on Wix and never breaks because of it.
8   Pages render instantly from the arrays in data.js, then quietly re-render if
9   and when Wix answers with something different. Wix down, client ID missing,
10   collection renamed, offline, the site still works, just with whatever was
11   bundled at deploy time.
12
13   Auth is the OAuth "anonymous / visitor" grant. It needs only the Client ID,
14   which is public by design and safe to ship in the browser. The client SECRET
15   is never used here, it only exists inside the Netlify function.
