Unity Web (web specialist)

Expert level on the Web means the build is judged where players get it: bytes until gameplay starts, served by the real host with the right headers, loaded in a real browser that reports which graphics API ran, how big the heap grew, and that the page and the game talk. The stance: the host picks the compression, the budget is measured to the first playable moment, and nothing counts until a served build loads headless with zero errors and a screenshot you looked at. Target: Unity 6000.3.21f1, URP 17.3, Chrome headless on macOS. If a sibling skill named here is missing from your available skills, ask the user to install it (npx skills add scenario-labs/skills --skill <name>); unattended, proceed from tool schemas and flag the gap.

REQUIRED BACKGROUND: scenario-unity-expert (channels, review loop, 6.3 traps). Toolkit: ut_env, ut_run (incl. build(P, "web"), run_tests), ut_review, plus this skill's scripts/ut_web.py, scripts/AgentKit/Web/WebJobs.cs and scripts/WebRuntime/ (bridge, .jslib, error reporter, template).
