v0.25.1

Added (API host)

• /avatar/:seed?packs=…&style=… — /avatar/:seed now parses packs (comma-separated pack ids) and style (masc | femme | neutral) query params. Unknown pack ids are silently skipped (engine ignores them). Pack order does not affect cached output — the PNG cache key normalizes by sorting.

Fixed (API host)

• PNG cache key extended to include packs + style so cached renders no longer collide across different pack/style combinations of the same seed.

Changed (API host)

• /docs/http-api documents the new packs and style rows in the /avatar/:seed query table, plus new example URLs (?packs=halloween, ?packs=office,mono&style=neutral).
• /random inherits the new params (it forwards every /avatar/:seed query through unchanged).

Notes

• Required by the upcoming Figma plugin update (fixes fill-mode rendering — plugin was sending the right options to the main thread but buildUrl() was stripping packs/mood/style before the HTTP request).
• Backward compatible. Existing <img src="https://api.navii.dev/avatar/alice"> URLs unchanged.
