openlogi-core 0.6.17

//! Brand constants shared across the workspace: the project's public URLs and
//! the `openlogi://` deep-link command vocabulary.
//!
//! Both live here, in the platform-free core crate, so the agent (which *emits*
//! tray deep links and renders help links) and the GUI (which *parses* the deep
//! links and renders the same help links) share a single source of truth — the
//! command names can't drift across the process boundary, and a repo move
//! touches one file instead of three.

/// [`DeeplinkCommand::as_name`], so the two sides cannot disagree.
