Foundation Day — DESIGN.md Spec, Brand-Sourced Color Palette, and Per-Slide Narratives

A change in direction. Stopped iterating on slide wireframes; started building the design system and content layer that should have come first. DESIGN.md scaffolded, 44 named colors imported (24 from the design tool + 19 from the live calmstorm.vc site CSS), 17 slide narratives written with structured YAML data and interpretive commentary.
