+Each successful `main` push also publishes a new chart to the `feedc0de`
+Gitea Helm registry. Scheduled builds refresh the image tags without

+repository and upgrading a release selects the image from the new chart:
 
 ```sh
 helm repo add brunner.ninja https://brunner.ninja/charts

+The chart repository tag follows the bundled Apache and PHP versions. The
+current image contains Apache 2.4.69 and PHP 8.5.11, so `v2.4.69-8.5.11`
+publishes chart `2.4.69-8.5.11`; later chart commits append the Git describe
+count and hash. CI checks the built image's versions against the base Git tag
+before publishing a chart.
