1. Native direction and movement

• [x] 1.1 Declare a shared native-left face direction for the built-in 🐈 and resolve it even through an identical string palette entry.
• [x] 1.2 Update accepted horizontal movement facing, including pushes and same-turn self-movement priority; keep blocked and vertical behavior stable.
• [x] 1.3 Reuse the native direction on the proof, Title, and INDEX surfaces without mirroring text or non-directional glyphs.

2. Verification and release

• [x] 2.1 Add unit regressions for built-in and mod palettes, horizontal turns, pushes, blocked input, Undo, reset, and reduced motion.
• [x] 2.2 Verify browser controls, rule changes, CommonJS mod loading, Undo, and right/left MIAU poses on desktop and mobile.
• [x] 2.3 Run the full Node suite, production build, strict OpenSpec validation, and update the public preview.
