Progressively enhancing like it’s 2003
summary
Fugu Greetings is an installable offline PWA that progressively loads only supported code via dynamic imports and demonstrates roughly nine modern browser capabilities actually wired up and working: Native File System API to open and save back to the original file, navigator.share with files (Web Share Level 2) to attach images, Contact Picker to import names, async clipboard for image copy/paste, Badging for a pen-stroke counter, Periodic Background Sync for daily backgrounds, Notification Triggers for scheduled reminders, Wake Lock and Idle Detection — all error‑handled and conditionally loaded.
