//! Plan Comptable Général (PCG) – French GAAP chart of accounts constants.
//!
//! PCG uses a decimal classification with classes 1–9:
//! - Class 1: Equity and liabilities (capitaux)
//! - Class 2: Fixed assets (immobilisations)
//! - Class 3: Inventory and work in progress (stocks)
//! - Class 4: Receivables and payables (tiers)
//! - Class 5: Financial / cash (financiers)
//! - Class 6: Expenses (charges)
//! - Class 7: Income (produits)
//! - Class 8: Special accounts (comptes spéciaux)
//! - Class 9: Analytical accounts (comptes analytiques)

/// PCG control and main account ranges (6-digit base).
/// First digit = class; next two = subclass; last three = account.
///
/// L’idée de base:
/// Un bail peut être compté de deux façons :
/// - Bail en « exploitation » (operating) —
///   On enregistre surtout les loyers en charges au fil du temps.
/// - Bail « finance » (finance) —
///   On considère qu’on « possède presque » l’actif.
///
/// La classification dépend du référentiel (US GAAP, IFRS, French GAAP).
