Overview

Central registry for theme Definitions. Lookup by ID returns a fully configured Definition object. Adding a new theme = registering it (OCP) — no existing code modified.

Built-in themes are auto-loaded from config/themes/*.yml on first access.

Usage:

Ea::Theme::Registry.lookup(":119")  # → Definition
Ea::Theme::Registry.register(my_def)
Ea::Theme::Registry.all             # → [Definition, ...]

.lookup(theme_id) ⇒ Ea::Theme::Definition

Look up a theme by ID. Returns the default theme when the ID is nil, empty, or unknown.

EA stores theme IDs with a leading colon (":119"). The lookup normalizes by stripping the colon.
