Show HN: Bento - An entire PowerPoint in one HTML file (edit+view+data+collab)

Bento is a single HTML file that allows for editing, presenting, and collaborating on slides without the need for cloud login or installation. It's designed to work offline and can be shared via email or Airdrop. The default deck is around 560 KB and can be transformed from existing pptx files using Claude or ChatGPT. Bento uses an encrypted relay for shared editing and is MIT licensed. Check it out at https://bento.page/slides/
