Grounds the visual design in the product's own subject matter (vital- signs monitoring) rather than generic dark-mode defaults: a signature "pulse" green tied to healthy status (the accent color and the "up" status color are the same hue - a steady green pulse reads as healthy, same convention as a cardiac monitor), a small ECG-trace brand mark, and a restrained pulsing-glow animation on healthy status dots (prefers-reduced-motion respected) as the one deliberate motion touch. Typography moves off the bare system-ui stack: IBM Plex Sans for UI text, IBM Plex Mono with tabular numerals for metric values (CPU/mem/uptime/latency), Space Grotesk used once for the wordmark - chosen partly for IBM Plex's own systems-monitoring heritage. Functional additions: - Light/dark toggle, independent of config.yml's theme.mode, persisted to localStorage with a blocking inline script to avoid a flash of the wrong theme on load; auto mode now genuinely follows prefers-color-scheme instead of hardcoding dark. - theme.customCssPath support via a new route handler that serves a user-mounted CSS file at runtime (can't be a build-time import, hence the targeted no-css-tags lint suppression), with a path- traversal guard since it's still reading from disk on every request. - Loading-skeleton state for widgets awaiting their first WebSocket result, distinct from both the error state and genuine no-data. Verified visually in Chrome: theme toggle switches instantly in both directions, a live docker widget's status dot and monospace metrics render correctly in both palettes, and config hot-reload still adds a new widget without a page refresh.
