// src/schema.jsx — v5 taxonomy + field schema seed.
//
// Defines window.DEFAULT_SCHEMA_V5 — the canonical v5 schema:
//   • 20 groups, 240 categories
//   • Three-layer field inheritance: common (workspace) → group → category
//   • 11 field types incl. itemRef + swatchRef + tag-as-multiselect
//   • Tags: 3 axes (performance, location, materialFamily)
//   • Row orthogonals: state, specMode, typeOrInstance
//
// Source of truth for content: design/library-categories-v5.md.
//
// Backfilled into appState.taxonomies by migrate-v5.jsx (Phase 3) if missing.
// Ids are stable. Renaming a category id breaks materials.category and
// schedule_row.category references. Add new ids freely; never rename.
//
// Inheritance rules (see schema-helpers.jsx):
//   fieldsForCategory(id) = commonFieldIds ∪ groups[cat.groupId].fieldIds ∪ cat.fieldIds
//
// Many field ids are reused across categories where the semantics match
// ("brand", "size", "finish"). Category-specific ids are prefixed where
// the concept is unique ("beam_angle", "leaf_material", "pan_type").
