## Unreleased

## 0.9.1 - 2026-08-07

### Fixed

- Aligned the PHP-side 2D physics compatibility contract with Lenga's positive-Y-down coordinate system and restored the default gravity vector to `(0, 980, 0)`.

## 0.9.0 - 2026-08-06

### Added

- Added `Lenga\Engine\Core\Random`, a gameplay-oriented random helper with an explicit pseudo-random engine and pure-PHP fallback for Web export compatibility.

P1 Badge Implement the gravity fix before releasing 0.9.1

This changes only a test fixture, not shipped package behavior, and even the fixture value is overwritten by Physics2D::setGravity() before the test reads it. Since Physics2D::getGravity() still returns the native bridge value and no src/ file changes in this commit, installing 0.9.1 cannot restore the advertised (0, 980) default for users relying on default 2D gravity; the actual runtime/source behavior needs to be changed and the untouched default asserted before publishing the release note.
