Browser Hub Demo
Screen Wake Lock API
This matters for recipes, workouts, navigation, barcode scanning, presentations, and any hands-busy task where the screen timing out breaks the flow.
Device control
What this unlocks
Keep the display awake during a task without forcing awkward tap-to-prevent-sleep hacks. Widely available in modern Chromium browsers and some mobile environments. Unsupported browsers simply continue using normal sleep behavior.

Only enable it when the user clearly asks for it.
