Previously .mobile-add-bar { margin-bottom: -80px } was hardcoded
to match .container { padding-bottom: 80px }. Now both reference
--m-container-pad-bottom so they can't drift out of sync.

@@ -46,7 +46,7 @@ public/
 - **Logging:** Use `require('./logger')` (or relative path). Never use `console.log/error` in backend code. Use appropriate Pino levels: `debug` for verbose/diagnostic data, `info` for operational status, `warn` for retries/degraded state, `error` for failures, `fatal` for startup crashes.
 - **Frontend JS:** `console.error` is fine in `public/js/` — runs in browser, no Pino.
 - **Commits:** Conventional commits (`feat:`, `fix:`, `refactor:`, `chore:`, `ci:`).
-- **Releases:** Manual version bump — edit `version` in `package.json` + `package-lock.json`, commit as `<version>`, tag `v<version>`, push commit + tag (`git push origin main v<version>`). Triggers `.gitea/workflows/docker-build.yml` which builds and pushes the image. Auth uses repo secret `PACKAGES_TOKEN` (PAT with `write:package`) — the auto-injected `GITEA_TOKEN` does not have effective registry access.
+- **Releases:** Automated via `.gitea/workflows/release.yml` on push to `main`. Workflow scans conventional commits sedan senaste `v*`-taggen och bumpar strikt semver: `feat:` → minor, `fix:` → patch, `!:`/`BREAKING CHANGE` → major. Andra prefix (`chore:`, `docs:`, `ci:`, `refactor:`, `style:`, `test:`) bumpar inte. Workflow:n uppdaterar `package.json` + `package-lock.json`, committar som `<version>`, taggar `v<version>` och pushar. Tag-pushen triggar `.gitea/workflows/deploy.yml` som (1) bygger + pushar image till `gitea.shcizo.se/shcizo/pdga-rating:<tag>` + `:latest`, sen (2) anropar `package-updater-action` mot `updater.shcizo.se/update`. Required secrets: `PACKAGES_TOKEN` (PAT med `write:package` + repo-push-scope — används av både release.yml för att pusha main/tag och deploy.yml för registry-auth; auto-injicerade `GITEA_TOKEN` triggar inte cross-workflows och saknar effective registry-access) och `UPDATER_API_KEY` (för updater-endpointen). Action-repot `shcizo/package-updater-action` refereras via full Gitea-URL (`https://gitea.shcizo.se/...`) eftersom `uses:` defaultar till GitHub. **Manuell tag** är fortfarande möjlig om release-workflow:n skippas eller behöver kringgås — pusha bara `v<version>`-tag direkt.
 - **Scraping:** Two strategies per entity: direct HTTP (fast, preferred) with Puppeteer fallback (stealth plugin for anti-bot). Rate limiting must be respected.
 - **Database:** Migrations run automatically on startup in `db.js`. Schema changes go there.
 - **Templates:** EJS with shared layout in `views/partials/`. Pages use HTMX for dynamic content loading.
