Fast flashing block
Should be picked up through fast CSS animation timing.
Extension lab note
Lavendar Test Page
This page is meant for controlled extension testing. It includes true flashing surfaces, generated video clips with different motion intensity, calmer motion that should stay visible, and Giphy embeds so you can check the extension against a real-world source.
Keep screen brightness low while testing, and close the tab if anything feels uncomfortable.
- The fast flashing block, blinking feed card, color-flash video, flashing Giphy GIF, and flashing Giphy embed should blur.
- The fast-motion demo video should blur, while the slow-motion demo video should stay visible.
- The pulsing panel, static image, and calmer Giphy GIF and embed should stay visible.
- The inserted flashing feed item should get picked up shortly after it appears.
Pulsing animated panel
This moves quickly, but it should not be treated like a flash or strobe.
Static image control
This card keeps a flashy-looking filename but should stay unblurred because it is static.
Fast-motion video
This generated clip has large frame-to-frame movement and should now blur.
Slow-motion video control
This generated clip changes more gently and should usually remain visible.
Color-flash video
This demo rapidly swaps saturated colors with a mostly stable layout and should blur.
Giphy flashing embed
Uses a real Giphy iframe so the extension can be checked against embed content.
Giphy flashing GIF
This uses a direct Giphy GIF URL so the animated-image path can be tested.
Giphy calmer loop
This real Giphy loop should stay visible unless it actually contains rapid flashes.
Giphy calmer GIF
This direct Giphy GIF should stay visible unless the animation is truly intense.
Live feed
Feed card with a flashing preview block to simulate dynamic social content.
Normal item
This one should stay unflagged so you can compare behavior side by side.
Dynamic insert zone
