-- SpellData_Buffs.lua
-- THE curated BUFF spell table + the shared spell-data engine, single source
-- of truth for:
--   * the buff spell search suggestions (SpellSearchBox.lua),
--   * the External Defensives group ("External Defensive" category),
--   * the Personal Defensives group ("Personal Defensive" category).
-- Tagging a spell with one of those categories ADDS it to the matching
-- group's Defensive List (same-named IDs merge into one checkbox row).
--
-- Entry forms: a plain spellID, or { spellID, "Category" }. Every entry
-- needs its trailing comma. Categories render as a gold suffix in the
-- search rows; only the two defensive categories drive group membership.
--
-- Base list: a curated per-class player-buff table plus this addon's own
-- tracked spells.
--
-- This file also owns the shared engine (ns.SpellData) used by the sibling
-- data files SpellData_Debuffs.lua and SpellData_AbilitiesItems.lua. Those
-- register their own class-keyed tables via ns.SpellData.Register(kind, SPELLS).
-- Each "kind" ("buff", "debuff", "ability", "item") gets its own flattened
-- list + by-id lookup (ns.SpellData.KINDS[kind] = { FLAT=, BYID= }). The buff
-- kind's FLAT/BYID are ALSO exposed as ns.SpellData.FLAT/BYID for backward
-- compatibility (the defensive / Bloodlust / Time Spiral groups read those).
