Clicking the CPU pill opens a popup listing the highest-CPU processes,
refreshed live while open. services/topproc.sh computes top-style per-process
CPU% and mem% from two /proc snapshots and prints one ranked frame per run;
SysStats streams it only while procPollEnabled (drawer open), so the bar pays
nothing at rest.
CLAUDE.md documents the architecture and the runtime constraints discovered
here (helper scripts must be git-tracked for `nix run`; single-shot + exit to
flush stdout; bash+coreutils only; StdioCollector/Timer don't fire in this
Quickshell build; fixed-size popup to avoid stale-buffer on resize under Sway).
