// Magic items — Open5e SRD import.
//
// Per the open5e integration plan, magic items are the one genuinely net-new
// surface: EquipmentDef is a flavor ladder, not a structured magic-item table,
// so there is nothing to extend. This file is the single new, non-dnd_-prefixed
// table the plan allows for them.
//
// Like the bestiary staging table, this is a vendored *reference registry* —
// 237 SRD magic items with classified Kind/Rarity/Slot/attunement and a
// rarity-bracket sell value. It is deliberately NOT wired into the zone loot
// tables or Luigi's shop yet; that integration is a separate follow-up pass.
// buildSRDMagicItems() is the generated dump (see magic_items_srd_data.go);
// magicItemOverlay is the hand-authored refinement layer that wins on ID
// collision, mirroring the spell- and bestiary-import pattern.

// MagicItemKind is the coarse Open5e item category — the first word of Open5e's
// free-text "type" field, normalised.
