+        <section id="permissions"><h2>5. Why Hudra needs browser permissions</h2><p>Hudra requests only the access needed to provide its presentation features:</p><ul><li><code>activeTab</code> provides temporary access after you click Hudra or use its shortcut. Hudra uses it to inspect the selected tab and show an explanatory notice when a page is unsupported.</li><li><code>scripting</code> injects Hudra's packaged page-detection and presentation code into the selected lesson page. No remote code is downloaded or executed.</li><li><code>storage</code> retains only temporary session metadata needed to coordinate and restore an active presentation. Lesson content and generated previews are not written to extension storage.</li><li><code>system.display</code> detects usable displays and arranges presenter and audience windows.</li><li>Host access allows Hudra to operate on supported QLearn and Instructure-hosted Canvas lesson pages. It is required for the new audience tab created in dual-screen mode because the original tab's temporary <code>activeTab</code> grant does not transfer to that tab.</li></ul><p>Hudra activates only after you click its toolbar button or use its keyboard shortcut.
