Adds a knowledge-card scene (vertical and square social cards) and
four presentation styles beside the original warm-white deck: a dark
pitch deck, a paper-white lecture deck, a minimal keynote and a
gradient-tech deck with glassmorphism built from opaque composited
stops — the linter drops alpha channels, and a truly translucent card
would exempt its text from contrast checking forever. Every palette
pair ships with measured WCAG ratios baked into the generators, and
low-contrast probe documents prove the audit actually fires on each
template family.
