fix: hide desktop table-toolbar on mobile + fix sparkline overflow (#16 )

- Add .table-toolbar to mobile hide list (was rendering duplicate 'TRACKED PLAYERS' header above the mobile section-head) - Change .m-card__body grid to minmax(0, 1fr) auto so the stats column can shrink below content size - Add min-width: 0 to .m-card__stats for proper grid shrinking - Remove grid-row: span 2 from .m-card__sparkline (single-row grid) - Remove overflow: visible from .m-chart-spark so the end-dot stays within the SVG viewport
style: convert var to const in sparkline toggle block (#16 )

 - **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:** 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/deploy.yml` which (1) builds and pushes the image to `gitea.shcizo.se/shcizo/pdga-rating:<tag>` + `:latest`, then (2) calls `package-updater-action` against `updater.shcizo.se/update` to roll out the new image. Required secrets: `PACKAGES_TOKEN` (PAT with `write:package`, for registry auth — the auto-injected `GITEA_TOKEN` does not have effective registry access) and `UPDATER_API_KEY` (for the updater endpoint). The action repo `shcizo/package-updater-action` is referenced via full Gitea URL (`https://gitea.shcizo.se/...`) since `uses:` defaults to GitHub.
 - **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.

Author	SHA1	Message	Date
Samuel Enocsson	4dc429b961	fix: hide desktop table-toolbar on mobile + fix sparkline overflow (#16 ) - Add .table-toolbar to mobile hide list (was rendering duplicate 'TRACKED PLAYERS' header above the mobile section-head) - Change .m-card__body grid to minmax(0, 1fr) auto so the stats column can shrink below content size - Add min-width: 0 to .m-card__stats for proper grid shrinking - Remove grid-row: span 2 from .m-card__sparkline (single-row grid) - Remove overflow: visible from .m-chart-spark so the end-dot stays within the SVG viewport	2026-05-22 21:44:22 +02:00

Samuel Enocsson	b51c47dc4c	fix: address mobile UI review findings (#16 ) - Hide desktop .card-section on mobile, add .m-search-input with same HTMX attrs for mobile course search (fixes horizontal overflow) - Remove dead layoutCount var and .m-layouts-pill block in course-cards - Remove dead 768px breakpoints from players.css (table hidden at 880px) - Move .mobile-section-head inside else-block for empty state in both ratings-cards and course-cards (fixes section head showing on empty) - Add tabindex, role=button, aria-expanded, onkeydown to .m-card and .m-course-card; toggle aria-expanded in JS toggle functions - Fix data-history attribute to use <%= (HTML-escaped) instead of <%- - Convert var to const/let in all new/changed JS blocks	2026-05-22 21:27:05 +02:00

Samuel Enocsson	96edc606d3	fix: offer refresh button when round history is empty When a player has rating_history (graph) but no round_history (per-round detail), calculating a target produced a dead-end error. Now the modal detects the NO_ROUNDS case and shows a button that triggers the existing refresh-round-history endpoint and re-runs the calculation on success. Handles the 24h rate-limit and other refresh errors explicitly.	2026-05-22 13:32:02 +02:00
