Current evergreen browsers can use the local chart, region selector, and study panels.
Browser Readiness
WeAcuRe should remain usable on current Chrome, Edge, Firefox, and Safari releases from roughly 2020 or later. Older browsers receive a limited-page notice instead of the full chart experience.
Current browser scope
Browsers without module support receive a simple status message.
Static pages and the main app should avoid horizontal overflow in mobile smoke tests.
Before browser-facing changes
- Run the compatibility check before using newer JavaScript or CSS features.
- Keep forms, buttons, links, and region controls keyboard reachable.
- Use visible labels, headings, and aria labels for interactive chart areas.
- Run desktop and mobile smoke tests after layout, navigation, or visual changes.
Before public launch
- Confirm favicon, manifest, canonical URLs, static CSS, and error pages render correctly.
- Confirm no static page has broken images or horizontal overflow.
- Keep the legacy browser notice visible when module scripts are not supported.
- Document any unsupported browser behavior in plain language.
