## Description

PreferencePulse is a Firefox add-on for auditing how well a page's CSS responds to user preference media features.
Many teams support dark mode or motion reduction partially, but coverage is often inconsistent across stylesheets.
PreferencePulse scans accessible CSS rules and reports usage of key media features such as <code>prefers-reduced-motion</code>, <code>prefers-color-scheme</code>, <code>prefers-contrast</code>, and <code>forced-colors</code>.
