rareindex-mark.svg — the mark (64×64 grid, 14 px radius): a cut stone (crown, girdle, pavilion) whose facets are drawn by an ascending index line. Ink #0B0F19, gold #F1D08A → #C9963F, mint #2FB673 → #5FE3A1.
rareindex-logo.svg / rareindex-logo-dark.svg — horizontal lockups (mark + wordmark + tagline) for light and dark backgrounds.
Favicons and PWA icons are generated from the mark by apps/web/scripts/brand-assets.mjs (node scripts/brand-assets.mjs from apps/web).
Minimum size for the mark: 16 px (favicon). Do not recolour the stone; the wordmark may be set in a single colour.
