# shot — one-call HD screenshot that prints ONLY a PNG path (keeps base64 out of the

#   shot                       # whole workspace (all panels)

# WHY: `adom-cli hydrogen screenshot ...` prints a ~300 KB base64 dataUrl to stdout.
# Piped raw into an AI conversation that's ~85k tokens of noise per capture, plus a
# second decode step. This wrapper decodes in-line and emits ~20 bytes; the AI then
# Reads the path (images are attached efficiently by the Read tool).
