In `@script.js`:
- Around line 127-131: The handler on fanSpeedInput currently calls
sendDeviceUpdate on every 'input' tick causing many network writes; update it to
only perform the DOM update immediately (fanSpeedValue.textContent) but debounce
or throttle the network call (wrap sendDeviceUpdate('fan-main-hall', { speed })
with a debounce/throttle helper) or alternatively switch the network write to
the 'change' event so the backend is contacted only once after the user releases
the slider; target the listener attached to fanSpeedInput and the
sendDeviceUpdate invocation to implement this change.
- Around line 102-117: sendDeviceUpdate currently performs an optimistic local
update then awaits rainMakerClient.updateDevice without handling failures;
capture the previous device state (const prev = state.devices[deviceId]) before
mutating, wrap the call to rainMakerClient.updateDevice in a try/catch, and on
error revert state.devices[deviceId] back to prev, call appendLog with the error
details and a clear failure message, and return or propagate a failure indicator
(e.g., return false or throw) to avoid unhandled rejections; keep the existing
connected-check and success path (use result.deviceId/result.endpoint) but
ensure any thrown error from updateDevice is caught and handled.
In `@styles.css`:
- Line 25: The font-family declarations (property "font-family" using the quoted
family name 'Inter') are triggering the stylelint rule font-family-name-quotes;
remove the unnecessary quotes so the family appears as Inter, and apply the same
change to the other occurrence referenced (the second "font-family: 'Inter',
sans-serif;" instance) to make both declarations lint-compliant.
- Around line 116-125: The .button rule (and other interactive control classes
around lines 273-314) lacks an explicit :focus-visible state which harms
keyboard users; add a clear, high-contrast :focus-visible style for .button (and
the same interactive classes) that does not rely solely on :hover — e.g., apply
a visible outline or distinct box-shadow and ensure it respects the existing
transition (transform/box-shadow/background) and preserves border-radius and
padding so keyboard focus is obvious and consistent with the visual design.

Handle cloud update failures to prevent unhandled rejections and stale local state.
sendDeviceUpdate assumes success. Once wired to real RainMaker APIs, failures here will surface as unhandled async errors and keep optimistic state without rollback.

Avoid sending a cloud write on every slider tick.
Using input for network sync can generate a burst of requests while dragging and overload backend endpoints.

Add explicit keyboard focus styles for interactive controls.
Custom-styled controls currently lack a strong :focus-visible treatment, which makes keyboard navigation hard to track.
