- reframe headline from the 2.0-collapse era to current 2.1 state; drop the
bookmarks provider from the compiled-in lists (it's deferred, not shipped)
- add a Performance section with informational warm-daemon latencies
- add a demo GIF (calc / converter / web / power) and a power-menu screenshot,
captured with synthetic providers only so no user data is shown; embed the
GIF as the hero image
