// owned-check.js — shared lookup against data/owned.json.
//
// data/owned.json is the single-source-of-truth for "domains Steve already
// owns". Both register.js (refuse re-registration) and honeypot-v2.js (refuse
// to use as bait) consult this. File may not exist yet — that's a clean
// "nothing owned" answer, not an error. Tolerates both shapes:
//   ["foo.com", "bar.app"]                   (bare array)
//   { "domains": ["foo.com", "bar.app"] }    (wrapped object)
