Doctor tripwire was self-hiding under waybar (PATH miss / weak glyph). Call nomarchy-doctor by store path, strip ANSI tooltips, use + format + signal 10 (generated and whole-swap). theme-shot asserts class:bad, guest btop.theme, and pokes RTMIN+10 before desktop shots. V2: theme-shot green for rose-pine, summer-night, catppuccin, everforest, vantablack; bar crops show the red alert-circle. btop TUI visual is softGL-blocked (Ghostty) → HARDWARE-QUEUE. Closes #51 and #52.

# Themed-desktop capture harness (item 28 slice c) — boots the full
