+# metrics.sh full|compact — the status-right system segment in ONE process per refresh.
+# (tmux used to spawn net dl, net ul, cpu, mem and temp as five separate #() jobs per tick.)
+# Prints #[fg=…] style markers, which tmux honours inside #() output.
+#   full    : net dl · net ul · cpu · mem · temp   (temp vanishes when no sensor exists)
+#   compact : cpu · mem
+# CPU and net are averaged over the interval since the PREVIOUS refresh: the /proc totals
+# persist in $XDG_RUNTIME_DIR state files, so no sleeps and the value covers the whole
+# status-interval. First run (no state yet) shows the since-boot average. Glyphs are Waybar's:
+# cpu U+F035B, memory U+F0F86, thermometer U+F050F, download U+F019, upload U+F093.
