| # Lighthouse CI gate (Wave 3 polish, 2026-05-21). | |
| # | |
| # Builds the static site, serves it locally, runs Lighthouse against the | |
| # prerendered HTML for each of the five most-trafficked public routes, | |
| # and fails the PR when any category drops below the configured floor: | |
| # | |
| # perf >= 90, a11y >= 95, best-practices >= 95, seo >= 95 | |
| # | |
| # A green Lighthouse score on the homepage is meaningless if the SSR | |
| # splice broke /docs or /pricing — every prerendered surface is checked. | |
| # Mobile emulation (the default) is the harshest test, so we use it. | |
| # | |
| # The fail-on-budget config in .lighthouserc.json holds the thresholds. | |
| # Update both this workflow and that file together when bumping a floor. | |
