Every mark uses fill=currentColor → maps to system CanvasText in forced colors; the ForcedColors story passes axe. Pulse is disabled under prefers-reduced-motion. All Logo tests pass. Re-verified 2026-07-13 for stable promotion: AT snapshots committed for all required stories; `animated` is now a controlled signal (pulses while true) rather than self-hover, driven by SiteHeader's link-hover state. Swapped into SiteHeader (production consumer on every page) with byte-for-byte parity vs the prior inline mark — identical viewBox 0 0 395 323, geometry, dt-logo-pulse keyframes, badge scale, currentColor tokens; verified live in the running app (rest/hover/both themes). Extended 2026-07-22 (content-atom elevation): custom-image path (`src`) renders a native <img> — accessible name from `title` via alt, decorative maps to alt=\"\" + aria-hidden; animated/badge stay built-in-mark-only so no motion applies to custom images. 2026-07-22: `badge` renamed to `background` (same lime-circle rendering; prop name now says what it does) before the first npm publish of the Logo export, so no published React API breaks.",
