What changed

Clarified the public website copy in docs/index.html so the site can stand on its own better as the main entry point.

Specifically:

• made the direct-care decomposition explicit as a two-step process, including the pooled residual subtraction
• added a plain-English explanation of why the bridge benchmark and annual-hours benchmark differ so much in level
• defined the outside-option wage more clearly in the demand-IV explainer
• added the missing four-state licensing-shock supply-IV pilot result numbers to the website

Why

Several core method explanations were clear in the README and report artifacts but still too implicit or incomplete on the website. Since the site is the main entry point, the public wording needed to carry the explanation directly.

Validation

• python3 HTML parse check on docs/index.html
• local preview served from docs/ and verified with curl -I http://127.0.0.1:55094/

Impact

Readers can now understand the benchmark adjustment, the benchmark-level gap, the demand instrument, and the supply-IV pilot without leaving the site for the README.
