1.0.0 — launch

• Preview a thumbnail in a simulated home feed, search results, suggested sidebar and a mobile frame — light or dark.
• A/B compare up to four versions in the same feed slot.
• Squint test: blur everything to check the thumbnail still reads at a glance.
• Export any preview as a PNG, and keep the last 50 previews locally.
• Replace the image from the preview page by button or by dropping a file anywhere on it.
• Everything free. One permission, no host access, and no network requests while in use.
