Notification sound
Flowra has two sounds, and both are generated on the spot with Web Audio, with no files: a double chime for a new message and a triple sparkle for an assistant reply.
In codelib/sound.ts
Live example
If you didn't hear anything, sound is turned off in notification settings or in this browser, or this was your first interaction with the page.

700msTwo sounds within this window become one- Browsers don't allow sound before the first interaction; a sound requested before then doesn't play and doesn't come later either.
- People turn sound off in notification settings, and the choice stays on the account.
- Don't add new sounds; every extra sound means people turn them all off sooner.
