- README points to demo/ as an auto-generated theme preview.
- Bump "60+ / 61 themes" references to the actual 65.
- Record Phase 7.5 in roadmap and list demo.yml + demo/ in layout.

 - An attempted repo rename to `tiennm99/ghstats-cards` was committed and reverted (commits `399a3dc` + `8bd2128` on record) — GHCR path immutability and the cost of breaking pinned consumers outweighed the Marketplace-name cosmetic benefit.

+- Output lands in `demo/<theme>/`, with an auto-generated `demo/README.md` TOC so reviewers can browse palettes side-by-side with real data instead of cloning and running the CLI.
+- Loop prevention: workflow skips pushes that only touch `demo/**`, `output/**`, `**.md`, or `LICENSE`; `GITHUB_TOKEN`-driven pushes don't retrigger workflows by design.

-`theme.Theme` is a pure-data struct — no methods. Cards pull `t.Background`, `t.Text`, `t.Title`, `t.Accent`, `t.Muted`, `t.Stroke`, `t.StrokeOpacity`. The 61 palettes live in a map keyed by snake_case ID.

 Light themes (`default`, `github`, `nord_bright`, etc.) use `StrokeOpacity: 1` with a visible stroke color; dark themes often use `StrokeOpacity: 0` or a stroke that blends into the background.
