kvmd-fullscreen

Floating browser-fullscreen button for PiKVM. Clicking enters browser fullscreen so keyboard shortcuts (Alt+Tab, Ctrl+Esc, Win key, etc.) route to the target machine instead of the host browser.

Position

Top-right, 2px margin (coordinates with kvmd-paste-clipboard which sits at right: 34px).

CSS customization

Override in /etc/kvmd/web.css:

:root {
    --cs-fullscreen-top: 2px;
    --cs-fullscreen-right: 2px;
    --cs-fullscreen-size: 22px;
}

How it works

Patches session.js to call document.documentElement.requestFullscreen(). Listens for fullscreenchange to swap the icon between enter/exit states.
