// Official brand marks — the `logo` type's provider tiers, tried in registry
// order. Every tier was verified against a 54-brand stress test (2026-07,
// 100% cascade hit). Hit counts below are a snapshot of that run — they
// drift as the alias/org maps grow; re-run the stress test to refresh them.
//
//   1. svgl          — official full-color vector SVGs (+ wordmark variants);
//                      40/54 first-hits. Search is substring-based, so
//                      entities go through alias normalization first
//                      ("nextjs" never matches "Next.js" raw).
//   2. simple-icons  — monochrome official glyphs; caught the long tail the
//                      others miss (nike, visa, toyota, wechat, bytedance).
//                      Pinned CDN build for determinism.
//   3. github avatar — the org's official logo for brands with a GitHub
//                      presence. Known orgs only: guessing a login risks a
//                      same-named personal account.
//   4. domain favicon — small-raster last resort (DuckDuckGo ip3). Responses
//                      under ~500B are DDG's globe placeholder, not a hit.
//
// HeyGen asset search is deliberately absent: for brand queries it returns
// generic look-alike icons (0/3 in testing) — worse than a miss. A total miss
// falls through to resolve's normal failure path (`no provider could resolve
// logo`, exit 1).
