/**
 * Hand-curated spell-slot / cantrip / repertoire progression overlay.
 *
 * WHY HAND-CURATED: Foundry pf2e encodes slot tables in description prose, not machine-
 * readable rules (Pitfall #6 / verified 2026-04-27 against `wizard-spellcasting.json`).
 * NLP-parsing prose is fragile; the canonical PF2e tables fit in ~300 lines and are stable
 * across reprints.
 *
 * SOURCE: Archives of Nethys — Pathfinder 2e Player Core + Advanced Player's Guide
 * (https://2e.aonprd.com). Per-class spell-slot tables, cantrip counts, and repertoire
 * sizes (spontaneous casters only).
 *
 * SCOPE: 16 D-16 classes (Core + APG). Plan 03 shipped the type definitions and Wizard
 * fully populated as the worked example. Plan 03b appends entries for the remaining
 * 6 caster classes (Cleric, Druid, Witch, Bard, Sorcerer, Oracle) and the empty-array
 * entries for non-casters (confirmed empty per design).
 *
 * SPONTANEOUS vs PREPARED: Spontaneous casters (Bard, Sorcerer, Oracle) get
 * repertoireIncrement entries on level-up. Prepared casters (Cleric, Druid, Witch, Wizard)
 * get spellSlotIncrement only. Both get cantripIncrement at L1.
 *
 * SLOT-PROGRESSION CADENCE (all D-16 full casters share this base shape):
 *   L1 : +2 grade-1 slots (3 for spontaneous Sorcerer/Oracle), +5 cantrips
 *   L2 : +1 grade-1 slot
 *   L3 : +2 grade-2 slots
 *   L4 : +1 grade-2 slot
 *   ... continues +2 / +1 per spell-grade through L18 (+1 grade-9)
 *   L19: +1 grade-10 slot (Magnum Opus / capstone equivalent)
 *   L20: no further slot increment (capstone is qualitative)
 *
 * REPERTOIRE CADENCE (spontaneous casters, Plan 03b model):
 *   L2..L19 each grant +1 spell known (`repertoireIncrement: 1`). The recompute pipeline
 *   in Plan 04 distributes that capacity across known spell grades; this overlay simply
 *   tracks "new spell known this level" so the wizard can prompt the player.
