/**
 * E13 — the dates that split the campaign calendar into phases, in one
 * client-safe module, on the precedent of `territorialClassAnchors.ts`: the
 * planner's copy and the eligibility evaluator both read from here, so moving
 * a phase is a one-line diff in one file.
 *
 * Cuts are ILLUSTRATIVE of the 2026 calendar the research report describes
 * (construção jul–ago, consolidação set, ativação na última semana), anchored
 * on two real dates — the legal start of the campaign and the vote — but the
 * exact turn of "consolidação → ativação" is a judgement call the coordination
 * makes, not a statute. Recalibration is E15's job, same as E10's anchors.
