…ds 4→6 Two parallelism dials to cut wall-clock CI time: - services/frontend/playwright.config.ts: fullyParallel=true and workers=process.env.CI ? 2 : undefined. Local runs use Playwright's half-CPU default; CI runners are 2-vCPU so 2 workers fits without over-subscription. - .github/workflows/ci.yml: SHARD_TOTAL and the matrix go from 4 to 6. The build.gradle.kts sharding logic (stable FQCN-hash partition) is shard-count-agnostic — just feeding it more buckets gets us six ~equal slices instead of four.
