Cell Automaton Engine — 0.2.1

Learning

• New "Learn" section with three chapters: Controls, Visual Rule, Scripting.
• Text descriptions of both individual features and how they combine with each other.
• An interactive hands-on walkthrough for each chapter — a narrator guides you step by step right inside a live session and waits until you actually perform the action (add a cell type, bind a constant, open a node's kind list, etc.), instead of just paging through text.

"Play" screen

• Completely redesigned: a mode switch on the left, three buttons (New Project / Examples / Open File), and a short info panel on the right.
• The examples list now opens right in the same window instead of the documentation, and hides again on a second click.
• Fixed: the examples list only showed 5 out of 10 — added scrolling.
• Fixed missing preview icons for some examples.
• Added a loading spinner when opening the examples list — removes the brief UI stutter.
• The screen is now translated into all 5 supported languages (EN/RU/ES/DE/FR).

Editing

• Numeric fields (constants, Script and Visual Rule node parameters) can now be edited manually from the keyboard, not just by dragging.
• Fixed a dropdown-list selection bug: clicking a list item that overlapped a button underneath would trigger the button instead of the item.

Performance

• Visual Rule is now computed in parallel — the simulation step is spread across CPU cores (safe, since each next-generation cell is computed purely from the old grid snapshot). Noticeably higher FPS on large grids.
• Optimized the DISTANCE node in Script: the nearest-cell search now expands in rings with early exit, instead of scanning the full bounding box. The tick-budget savings scale with how densely the target cells are placed (up to ~12x on dense grids).
