Make System panel top accent bar reflect CPU/memory/swap/disk tone

ROADMAP.md

@@ -264,3 +264,9 @@ Roughly in priority order:
 `v0.16.69` closes a gap flagged after reviewing the ZimaOS compose file: `compose.yaml`, `compose.release.yaml`, and `compose.zimaos.yaml` all documented `DATA_DIR_LIMIT_GB` and the `mem_limit`/`cpus`/`cpuset` resource-panel options in README/install.html but never actually carried them as commented-optional entries the way the marketing site's install guide showed -- someone copying a real compose file instead of the docs page got none of that guidance. All three now include the same commented-out block (env-var style in the two static compose files, `${VAR}`-substituted and wired through `.env.example` in `compose.release.yaml`). This also folds in the marketing site's `install.html`, which had drifted out of sync with an already-updated draft and was missing the same options on the user's machine -- resynced so the published guide matches what ships in the repo.
 
 `v0.16.70` fixes the Access Logs table (Administration > Logs, "Access requests"), the last page still on its own pre-unification CSS: `.log-table` pinned the Status and Duration columns with `position:sticky` and drew a divider `box-shadow` on each -- a horizontal-scroll affordance none of the other log-type pages use -- and left the Request column at a fixed width instead of stretching to fill the panel, so wide viewports showed an empty gap past Duration. Both are removed: the two trailing columns are back in normal table flow, and Request now takes `width:auto` to absorb the remaining space, matching how Gateway Events, Backup history, and the Audit log already size their last column. Purely a CSS change -- no markup, data, or behavior changes.
+
+`v0.16.71` fixes a Gateway Events / Audit log message that slipped past v0.16.66: the Hosted Site file-upload route ("Replace files") still wrote the old, un-prefixed `Files replaced for "<name>".` line instead of the `Hosted site "<name>" ...` convention every other Hosted Site action uses (created, enabled/disabled, deleted, and the field-level update summaries). It lived in its own route separate from the four `PATCH` handlers v0.16.66 touched, so it was missed at the time and only noticed once a user pointed out the log entry gave no way to tell which route type it belonged to. Now reads `Hosted site "<name>" files replaced.`, matching the rest.
+
+`v0.16.72` fixes the favicon not appearing in some Chromium-family browsers (reported: DuckDuckGo's browser showed the default globe icon while Safari showed the real one correctly). The app previously declared a single `<link rel="icon">` pointing straight at the 1018x1001, 396 KB source PNG with no `sizes` attribute and no `/favicon.ico` fallback -- Safari is forgiving about oversized, unsized favicons, but some Chromium-based browsers silently skip one that large rather than downscale it, and several also probe `/favicon.ico` directly regardless of what the `<link>` tag says. Added properly sized `favicon.ico` (16/32px, multi-size), standalone `favicon-16.png`/`favicon-32.png` with `sizes` attributes, and a 180x180 `apple-touch-icon.png`, all generated from the existing approved icon artwork and served automatically by the existing static file handler -- no server route or icon design changes.
+
+`v0.16.73` makes the Dashboard's System panel top accent bar reflect resource state, instead of always showing green -- pointed out after a screenshot showed CPU pinned at 100% (its own stat correctly shown in red) while the panel's top bar stayed the hardcoded `var(--green)` it always had. `renderHeroPanel()` now tracks the worst tone across CPU/memory/swap/disk (the same "warning" at 75%+ / "critical" at 90%+ thresholds each stat's own value and fill bar already used) and applies a `tone-warning`/`tone-critical` class to the panel, which `.system-panel::before` now reads instead of a fixed color. Network, uptime, and throughput don't carry a tone and are excluded from the calculation, same as before. Applies to the Dashboard's System panel only -- the Administration > System tab's equivalent hero grid has no top accent bar to react.
