Review comments at @Marketing/AppStore/generate.py:
- Around line 647-688: The artwork validation in check_config must use the same
effective caption-column width that render_artwork applies, including its
input-dependent limit. Share the column calculation between check_config and
render_artwork, then pass that effective width to fit_artwork_caption so
--check-config rejects any caption that would fail or be clipped during
rendering.

Use the render-time caption column in --check-config.
check_config validates captions against artwork_column_width(...), but render_artwork applies an additional input-dependent width limit. A valid artwork configuration can therefore pass --check-config while rendering raises ValueError from fit_artwork_caption (or clips the caption). Share the effective column calculation between both paths, or reject configurations that cannot produce a valid render.
