//! Shared utility functions used across routes and modules.
//!
//! Organized into focused submodules and re-exported flat, so existing
//! `crate::helpers::*` imports keep working unchanged:
//!
//! - [`http`], shared outbound client, client-IP, HTMX/ETag, toast headers
//! - [`db`], unique-violation (23505) mapping + unique-slug insert loop
//! - [`render`], Askama fragment rendering + HTML escaping
//! - [`billing`], Stripe fee estimation + timestamp conversion
//! - [`datetime`], schedule-datetime parsing
//! - [`integration`], CSRF-token convenience + MT discussion stats
//!
//! Formatting, crypto, and rate limiting live in their own top-level modules and
//! are re-exported here too, for the same backward-compatibility reason.
