browser-matrix-strategy-reference

Overview

A real browser matrix tiers browsers by traffic share, regulatory requirement, and team budget, then runs each tier at its own cadence - not "test on everything".

This skill is a pure reference consumed by the sibling execution skills: cloud-grid-e2e (BrowserStack / Sauce Labs / LambdaTest), the self-hosted selenium-grid-4-runner, and playwright-testing browser projects (bundled engines; references/browser-matrix.md). Capping the matrix and publishing the support statement is covered in references/compatibility-budget.md.
