Base64/braille decoder, DLsite/Steam product cards, link-health checker, and password auto-fill for kone.gg.
Why @match *://*/*:
The drag-to-decode feature (select any text → decode Base64/braille) is designed to work on any website, not just kone.gg.
Why @connect *:
The link health checker fetches user-provided URLs embedded in kone.gg articles (HEAD requests) to detect dead links. These URLs can point to any domain (mega.nz, gofile.io, arbitrary servers, etc.), so @connect * is required. Known fixed targets (DLsite, Steam, kio.ac) are also declared individually above.
