+/**
+ * Tech Store - Alexandria
+ *
+ * This store manages the "show technical details" user setting for the Alexandria app.
+ *
+ * Use case:
+ * - Used with the ATechBlock component to hide nostr-specific developer details (e.g., raw event blocks) behind a collapsed section.
+ * - Users can toggle visibility of these technical details via the ATechToggle component.
+ * - If a user is a nostr developer, they can set their profile to always show technical details by default.
+ * - The setting is persisted in localStorage and reflected in the DOM via a data attribute for styling purposes.
+ *
+ * Example usage:
+ *   <ATechBlock content={...} />
+ *   <ATechToggle />
+ *
+ * This enables a cleaner UI for non-developers, while providing easy access to advanced information for developers.
