// AI Toolbar – Layout & Behavioral Contracts
//
// Public interface under test: the CSS class contracts that govern the
// toolbar's visual zones, state-driven visibility, and interaction affordances.
//
// Philosophy: tests describe WHAT the toolbar does (two-zone layout,
// auth-gated AI section, destructive action distinction) — not HOW the
// internal JSX is structured. These tests survive refactors because they
// lock down the *behavior* (what classes produce what visual outcome)
// rather than the implementation (which element wraps which).
// ---------------------------------------------------------------------------
// ─── Zone class contracts ───────────────────────────────────────────────────
//
// The toolbar is divided into two visually distinct zones:
// 1. AI zone – identified by a primary-color accent (ring/border on primary)
// 2. Data zone – neutral utility surface, no accent color
//
// We capture the intended class sets here as source-of-truth strings so
// that both the tests and the implementation reference the same contract.
