Build a 3D fishing game in three.js

Task prompt given to the agent (headless, offline, synthetic fixture inputs): Scaled-down version of a 4-week game: in one pass build a small 3D fishing game as a single file index.html using three.js from https://unpkg.com/three@0.160.0/build/three.module.js (ES module import). Must include: a water surface and a dock/boat scene with lighting; click (or Space) to cast a line with a visible bobber; a random bite after a delay with a visual cue; a reel-in timing mini-game (press at the right moment or keep a meter in a zone) that can succeed or fail; at least 4 fish species with different rarity/weight; a HUD with catch log/score. Inspired by https://x.com/hakimieiqbal/status/2092194086073614342 (unverified; not checked with the author). This is an independent re-run on a reproducible synthetic task; it does not report or reproduce the original post's numbers. Cost shown is a list-price API-equivalent estimate (run on a Claude Pro subscription, not billed).

Success criteria: All automated rubric checks pass: imports three@0.160.0 module; no uncaught console errors in headless Chrome; water surface; dock or boat; lighting; cast + bobber; bite after delay; reel mini-game; >=4 species with rarity/weight; HUD catch log/score.
