README.txt

 - The script looks for JS dependencies relative to itself under ./js/
 - It reproduces the mini-program's getCommand(qr) wrapping and uses the bundled QR JS renderer
 - Default timezone for QR payload generation is Asia/Shanghai; you can override it with MINIAPP_QR_TIMEZONE
-
-Gitea CI/CD template:
-1) Add `.gitea/workflows/docker-cicd.yaml` to your repository.
-
-2) Repository Actions must be enabled:
-   - Repository Settings -> Enable Repository Actions
-
-3) Your runner should have a label like:
-   linux_amd64
-
-4) The runner host needs these commands installed:
-   - git
-   - docker
-   - curl
-
-5) Required repository variables/secrets:
-   Variables:
-   - PACKAGE_USER            -> optional; defaults to current repo owner. If your repo is under an organization, or the token belongs to another user/bot, set this explicitly to the token owner username.
-   - DEFAULT_BRANCH          -> optional, defaults to main
-   - IMAGE_NAME              -> optional, defaults to current repo name
-
-   Secret:
-   - DOCKER_TOKEN            -> personal access token with at least repository read + package read/write permissions
-
-6) What the workflow does:
-   - clones the current repo from Gitea
-   - builds the Docker image
-   - pushes it to the current Gitea instance package registry
-   - links the pushed container package back to the current repository
-
-7) Registry image naming:
-   {gitea-domain}/{owner}/{image}
-   Example:
-   gitea.example.com/myteam/miniapp_qr_portable_bundle:latest
