README rewritten for a fresh clone: working status, quick start with env-var table and per-stage commands, photo-taking guidance, a bring-your-own-shelves section (this repo carries the author's live data), tokenless workflows, and a dev section. New committed data/STUB_DATA.marker closes a real gap: the cache marker is gitignored, so a fresh clone had stub-derived to_add.csv with no guard — upload now refuses on either marker. Username docs: BGG_USERNAME in .env is the one place it's needed; config.toml is a fallback. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
