The prompt was too aggressive about light products on light backgrounds,
causing professional product photography on white backgrounds to fail
(e.g. L'Oreal cream jar on white). Now evaluates whether the product
is actually VISIBLE and DISTINGUISHABLE (via shadows, edges, texture,
contrasting elements) rather than failing on theoretical colour match.

Reverted loreal_static from 2-check (visual_readability_contrast) to
3-check setup (language_consistency, text_readability, background_contrast)
to avoid score dilution. Updated text_readability and background_contrast
prompts from POS-focused to digital marketing, and added critical hidden/
invisible text detection (black-on-black, white-on-white scanning).
