// 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).
