How to run

Open index.html at the repo root (hub) or any sub-project index.html. Or from the repo root:

python -m http.server 8080

Then visit http://localhost:8080/ or a folder such as http://localhost:8080/spreadsheet/.

Conventions

• Do not commit .env or secrets
• Ask before adding dependencies
• use gh cli to create/push the repo github.com/az9713/cursor-origin
• always have a README.md at repo root
• if any main html exists, make it a GitHub page and link it from README.md (GitHub strips iframes in README)
• Customer-facing docs: HTML. Do not ship Markdown as the customer-facing surface.
• Process record for the whole hub: development_journey.html
• Internal docs (plans, agent notes, specs for the agent): Markdown is fine.
• New apps go in a sibling folder (mini-linear/, later spreadsheet/, etc.), never overwrite the hub index.html
• Frozen product spec for an app: <app>/SPEC.md
