//! # Holocron
//!
//! A **declarative schema & query compiler** — one YAML file is the single source
//! of truth for both a database schema *and* a type-checked query catalog.
//!
//! Any query (in RSQL or YAML) is validated against the catalog **before it runs**,
//! with no database connection needed, because the YAML *is* the schema.
//!
//! This crate is currently a pre-implementation stub; see `holocron-seed/DESIGN.md`
//! for the full design and roadmap.

/// Returns the project's banner line.
///
/// Kept as a small documented function so the generated docs (`cargo doc --open`)
/// have real content to show while the compiler itself is being built out.
///
/// # Examples
///
/// ```
/// // The banner names the tool and its purpose.
/// let banner = "Hello from Holocron — a declarative schema & query compiler.";
/// assert!(banner.contains("Holocron"));
/// ```
/// Program entry point. Prints the project [`banner`].
