 ### Bump Version
 
+Creates or updates the version in `package.json`, commits it, creates a matching Git tag, and pushes both.
+
+Inputs:
+
+- `node_version`: Node.js version to use. Default: `24`
+- `release_line`: optional release line for dev builds. Format: `<major>.<minor>` or `<major>.<minor>.<patch>`. Overrides branch, PR target, inferred ancestor release branch, and `package.json`.
+- `gitea_token`: optional token used for checkout and push
+
+Branch and tag rules:
+
+- `main`: creates release tags from the latest commit message (`release/x.y.z`, `release/x.y`, `hotfix/x.y.z`) or falls back to a patch bump.
+- `release/<major>.<minor>` or `release/<major>.<minor>.<patch>`: creates the next beta tag for that release base, e.g. `v2.4.0-beta.3` or `v2.4.1-beta.3`.
+- all other branches: create a dev tag for the resolved release base using a UTC timestamp, e.g. `v2.4.0-dev.20260314153045`.
+
+Dev release line resolution order:
+
+- `inputs.release_line`
+- current branch if it matches `release/<major>.<minor>` or `release/<major>.<minor>.<patch>`
+- PR target branch if it matches `release/<major>.<minor>` or `release/<major>.<minor>.<patch>`
+- newest ancestor branch from `origin/release/*` (for feature branches created from release branches outside PR context)
+- `major.minor` from `package.json`
+
+If no release line can be resolved for a dev build, the action fails intentionally.
+
+Examples:
+
+Commit message examples on `main`:
+
+- `release/2.4.0` -> `v2.4.0`
+- `release/2.4` -> `v2.4.0`
+- `hotfix/2.4.1` -> `v2.4.1`
+
+Branch examples:
+
+- `release/2.4` -> next `v2.4.0-beta.N`
+- `release/v2.4.1` -> next `v2.4.1-beta.N`
+- feature branch in a PR to `release/2.4` -> `v2.4.0-dev.<UTC_TIMESTAMP>`
+- feature branch created from `release/v2.4.1` (without PR base) -> `v2.4.1-dev.<UTC_TIMESTAMP>` when the release branch tip is an ancestor
+- feature branch outside a PR with `package.json` version `2.4.0` -> `v2.4.0-dev.<UTC_TIMESTAMP>`
+- feature branch outside a PR with `release_line: 2.4` -> `v2.4.0-dev.<UTC_TIMESTAMP>`
