v1.4.0: Clawdiverse-inspired theme redesign

Warm off-white light palette, decorative geometric shapes,
category-coded peptide cards with tinted borders and pill badges,
larger hero typography with accent word, header CTA button,
and redesigned single-peptide detail page with meta card grid.

Dark mode stays default per user preference. Light mode gets the
warm treatment when toggled or via prefers-color-scheme.
