+- **v0.5.4 — Monitoring Page Frontend Fixes (4 bugs, frontend-only):**
+  - **Bug 1: Tooltip "Invalid Date"** — `items[0].parsed.x` unreliable across Chart.js versions. Fixed tooltip callback to use `items[0].raw.x` (direct {x,y} data access) with `parsed.x` as fallback.
+  - **Bug 2: Charts fill full width regardless of data density** — `setChartXBounds()` setting `min/max` at runtime was ignored because the scale was created without them. Fixed by including `min: now - defaultRangeMs, max: now` in the initial `chartOpts()` options. Now "7 nap" shows full 7-day x-axis with data clustered on the right.
+  - **Bug 3: Sysinfo values not consistently right-aligned** — `.sysinfo-grid` used `auto-fill` creating variable-width cells. Fixed to `1fr 1fr` (fixed 2-column). Added `align-items: baseline`, `gap: 1rem`, `white-space: nowrap` on labels, `font-weight: 600` + `word-break: break-word` on values. Removed redundant `<style>` block from monitoring.html (styles now in style.css).
+  - **Bug 4: Charts overflow on mobile** — Added `min-width: 0` on `.chart-box` (critical CSS grid fix), `overflow: hidden` + `max-width: 100%` on `.chart-wrap` and `.chart-wrap-bar`, `max-width: 100%` on canvas.
+  - **Controller version:** v0.5.4 — deployed and verified on demo-felhom.eu

 - **v0.5.1 — Monitoring Page Bugfixes:**
   - **Bug 1: Hostname** — `os.Hostname()` returns the container ID inside Docker. Fixed by mounting `/etc/hostname:/host/etc/hostname:ro` and reading it first in `sysinfo.go`. Now shows `demo-felhom`.
   - **Bug 2: Tooltip timestamps** — Chart.js tooltip callback used `items[0].parsed.x` (category index 0,1,2...) instead of `items[0].label` (actual timestamp). Index 0 worked by accident (`0 || label` falls through), but all other points showed 1970-01-01.
