Patch Changes

• #61 def57fd Thanks @copilot-swe-agent! - Add root-level preset.js shim for Storybook integration catalog compatibility

Patch Changes

• #59 1140eea Thanks @copilot-swe-agent! - Fix package.json metadata for Storybook integration catalog: switch icon from SVG to PNG, remove unrecognized "lit" framework, and add top-level main/types fields.

Patch Changes

• #57 378088c Thanks @copilot-swe-agent! - Update keywords in package.json to improve discoverability.

Patch Changes

• #54 a80cfd7 Thanks @copilot-swe-agent! - Add storybook-addons keyword as the first keyword in package.json so the addon is discoverable by the Storybook integration catalog.

Minor Changes

• #41 6d3e5eb Thanks @mattcosta7! - Add framework-agnostic support via new universal entry points and split decorator architecture.

  New entry points:

  • ./universal — non-React public API (universal decorator + core)
  • ./react — React-specific API with Profiler support

  New files:

  • core/preview-core.ts — shared PerformanceMonitorCore class
  • decorators/universal.ts — framework-agnostic decorator
  • decorators/react.tsx — React.Profiler bridge decorator
  • preset-universal.ts / preview-universal.ts — Storybook preset for non-React frameworks

  The React decorator stack is now [withPerformanceMonitor, withReactProfiler], where the universal layer handles browser-level metrics and the React layer adds Profiler integration.

Patch Changes

• #39 1f8f843 Thanks @mattcosta7! - Reorganize internal file structure: move performance-store and performance-types into core/, move performance-decorator, react-profiler-wrapper, and ReportReactRenderProfileContext into react/. Remove unused ./react and ./components subpath exports. No public API or behavioral changes.

Patch Changes

• #35 8bc7842 Thanks @mattcosta7! - Improve forced reflow detection by instrumenting CSS style property setters. Previously only layout-triggering getter reads were monitored, so write-then-read patterns using element.style.width = '...' or style.setProperty() were missed. The collector now intercepts writes to layout-affecting CSS properties (width, height, margin, padding, position, etc.) to correctly mark layout as dirty before a subsequent reflow-triggering read.

• #35 4a26caf Thanks @mattcosta7! - Fix Element Timing collector not clearing on reset or story switch. Entries from the browser's performance timeline persisted across resets because buffered: true replayed stale entries. The collector now tracks an epoch timestamp and filters out entries recorded before the last reset/start.

Major Changes

• #13 ab71326 Thanks @mattcosta7! - Fix cross-browser test failures, parallelize CI with browser matrix, and add automated release workflow with changesets
