# Account Settings Form — Run Notes

## Assignment

- Agent name: Luna
- Reasoning level: xhigh
- Skill mode: no-skill
- Active frontend skill: None
- Exact output directory: `<LOCAL_SAMPLE_ROOT>/luna-xhigh/no-skill/03-settings-form`

## Files created

- `index.html` — standalone semantic page shell and account settings form.
- `styles.css` — responsive, accessible visual states and reduced-motion rules.
- `script.js` — validation, dirty-state tracking, cancel/reset, simulated save lifecycle, and status announcements.
- `RUN.md` — run, trigger, verification, and limitation notes.

## Running

Open `index.html` directly in a modern browser. No build step or server is required.

External dependencies: None. The page uses only local HTML, CSS, and JavaScript; it loads no external fonts, images, scripts, stylesheets, or network resources.

## Save-state triggers

1. Edit any profile field or notification preference. The inline **Unsaved changes** warning appears.
2. In the **Save response** control, choose **Simulate success** (the default), then select **Save changes**. After a short local delay, the page announces **Changes saved** and the dirty state clears.
3. Choose **Simulate failure**, edit a field if needed, and select **Save changes**. After the local delay, the page announces **Could not save changes** and keeps the edits plus the unsaved warning.
4. Use **Cancel** while dirty to restore the last saved snapshot. The control is disabled when there is nothing to reset.

## Verification performed

- Static inspection of the full HTML, CSS, and JavaScript for semantic controls, complete labels, `aria-describedby` validation-message associations, local-only assets, and isolation to this directory.
- Thought-experiment coverage for required fields, malformed email, whitespace normalization, changing a checkbox back to its saved value, cancel after failed save, repeated save clicks, and navigation/before-unload warnings.
- Interaction logic review for keyboard order: skip link → settings navigation → email → display name → time zone → language → notification checkboxes → Cancel → Save changes → Save response.
- Responsive CSS review at desktop and mobile breakpoints, including min-width constraints, wrapping behavior, and horizontal-overflow prevention.
- Reduced-motion review confirms transitions and the saving spinner are suppressed by `prefers-reduced-motion: reduce`.

## Verification results

- Implementation checks: PASS by source inspection.
- Required/format validation: PASS by source inspection.
- Dirty, cancel/reset, success, failure, saving, and warning state logic: PASS by source inspection.
- Focus visibility, status announcements, and non-color state cues: PASS by source inspection.
- Desktop/mobile and no-overflow rules: PASS by source inspection.
- Network-dependent assets: PASS — none referenced.
- Generated-file isolation: PASS — all generated files are under the exact assigned output directory.

## Known limitations

- Save behavior is intentionally simulated with a local timeout; it does not persist settings to a server or browser storage.
- The browser's native before-unload dialog wording is controlled by the browser and may vary by browser/version.
