How It Works
One Character Carries the Operation
Each Unicode character (✦, ◆, ●) is a self-contained OCC carrier. The character is mapped to a registry JSON file that defines an entire operation — setup, install, or verify. The OCC Reader expands the character into a full runtime sequence.
✦The Registry Defines the Package
A small JSON registry maps each OCC character to its full payload. The registry is fetched once, cached, and reused. The OCC Reader (4,659 bytes) decodes the character and executes the corresponding operation — no external libraries, no CDN calls, no server writes.
localStorage Is the Install Target
This demo uses the browser's built-in localStorage API as a safe, sandboxed "file system." Setup saves environment data, Install saves the 6-file package manifest, and Verify reads both to confirm integrity. No server required. 100% browser-native. The full demo resets cleanly with a single localStorage.clear() call.
SOURCE CODE — OCC CARRIER FILE
<!-- CARRIER: three-code-install.html (~850 bytes) -->
<!DOCTYPE html><html lang="en"><head>
<meta charset="UTF-8">

The ✦ above expands into this entire installation demo. 850 bytes vs 12,000+ bytes traditional. The OCC reader is loaded once and shared across all 3 steps.
