/**
 * log10x_explain_mode — L2 surface.
 *
 * Explains ONE enforcement mode to the user in service-level plain
 * language before any action is taken. Called after the user picks a
 * mode from log10x_cost_options (or directly when the agent has already
 * determined the mode from context).
 *
 * Three compliance levers (same shape as log10x_start / log10x_cost_options):
 *   must_render_verbatim   — plain-text (NOT markdown) three-section card
 *                            with no pattern_hash references.
 *   must_ask_user          — "Apply" or "Preview" choice.
 *   forbidden_next_actions — locks apply tools and preview_filter until the
 *                            user explicitly picks one.
 *
 * routes_to:
 *   Apply   → configure_engine  (compact / offload / tier_down / sample / drop)
 *             null              (observe_only — no apply step)
 *   Preview → log10x_preview_filter
