The page rebuilt its whole header, bar and row list twice a second, so
numbers snapped, columns resized as digits changed, and rows swapped places
over a hundredth of a core.
- header values are tabular-width and tweened toward the newest sample
- machine-bar segments are keyed and reordered by flex order, so widths
animate instead of being recreated mid-transition
- rows are keyed DOM nodes updated in place, sorted on a 0.1-core grid with
the previous order as tiebreak, with hysteresis at the idle threshold
- tabs, banner and detail panes only re-render when their data changes
- poll every 700ms and drop repeat frames from the 2s sampler
bookmark.py puts a Vitals bookmark and a popup bookmarklet in the browser's
bookmark bar. It recomputes Chromium's bookmark checksum (MD5 over the
canonical node serialisation) and verifies it after writing, because a file
that fails that check leaves the browser showing an empty bar while the file
on disk still looks perfect. Refuses while the browser holds the profile,
keeps a timestamped backup, idempotent. install.sh runs it.
