// Package litigationplanner is the canonical Fristen / Verfahrensablauf
// compute engine — the deadline-rule model, the calendar arithmetic, the
// condition-expression gate, the sub-track routing, and the timeline
// composer that drives Paliad's /tools/fristenrechner,
// /tools/verfahrensablauf, and the per-project SmartTimeline.
//
// The package owns its types (Rule, ProceedingType, Timeline,
// TimelineEntry, CalcOptions, …) and exposes three interfaces for the
// stateful inputs: Catalog (proceeding + rule lookup), HolidayCalendar
// (non-working-day adjustment), and CourtRegistry (court → country/regime
// resolution). Paliad implements them against its Postgres database;
// downstream consumers (youpc.org) implement them against an embedded
// JSON snapshot of the UPC subset.
//
// See docs/design-litigation-planner-2026-05-26.md (t-paliad-292 /
// m/paliad#124) for the full design.
