Summary

@workflow/web-shared ships the trace viewer controls that downstream apps may include in their Tailwind content scan. The zoom controls used duration-[120ms], which Tailwind v3 can treat as an ambiguous arbitrary utility when scanning the package.

This PR changes those controls to duration-[time:120ms], preserving the same transition duration while giving Tailwind an explicit type hint. It also adds a patch changeset for @workflow/web-shared.

Verification

  • rg -n "duration-\[(?!time:)|ease-\[(?!easing-function:)" --pcre2 packages/web-shared/src
  • git diff --check
  • pnpm --filter @workflow/web-shared lint (blocked by existing unrelated Biome diagnostics in web-shared)
  • pnpm --filter @workflow/web-shared typecheck (blocked by existing unrelated attribute-panel.tsx type error)

@tomdale
fix(web-shared): type trace viewer duration utility
4354482 
Use Tailwind's typed arbitrary duration syntax for trace viewer zoom controls so Tailwind v3 consumers do not emit ambiguous utility warnings when scanning the package.

Column Definitions
  • Workflow Time: Runtime reported by workflow (completedAt - createdAt) - primary metric
  • TTFB: Time to First Byte - time from workflow start until first stream byte received (stream benchmarks only)
  • Slurp: Time from first byte to complete stream consumption (stream benchmarks only)
  • Wall Time: Total testbench time (trigger workflow + poll for result)
  • Overhead: Testbench overhead (Wall Time - Workflow Time)
  • Samples: Number of benchmark iterations run
  • vs Fastest: How much slower compared to the fastest configuration for this benchmark
