-- CoAClassColors.lua
--
-- Mirrors the live client's RAID_CLASS_COLORS into ShadowUF's private
-- profile.classColors table on init.
--
-- Why this is needed
-- ------------------
-- SUF stores its own classColors map (defaultlayout.lua:109) and looks
-- up colors via `ShadowUF.db.profile.classColors[class]` at e.g.
-- health.lua:149, tags.lua:246, empty.lua:53. Stock SUF only seeds
-- this table with the vanilla 10 (WARRIOR..DRUID + DEATHKNIGHT) plus
-- PET / VEHICLE.
--
-- The Conquest of Azeroth client (Voljin realm) ships
-- Interface/SharedXML/SharedConstants.lua with all 32 class
-- file_strings populated in _G.RAID_CLASS_COLORS — 10 vanilla + HERO +
-- 21 CoA customs (BARBARIAN, WITCHDOCTOR, DEMONHUNTER, FLESHWARDEN,
-- MONK = Templar, PROPHET = Venomancer, …). Other addons (Omen,
-- Details, DBM, …) read RAID_CLASS_COLORS directly so they pick the
-- realm-canonical palette automatically. SUF doesn't, so a guildmate's
-- CoA-class health bar falls through `colors[class] == nil` and the
-- bar reverts to the percent gradient.
--
-- Strategy
-- --------
-- After SUF's OnInitialize finishes (db.profile.classColors exists,
-- AceDB has resolved the active profile), copy any RAID_CLASS_COLORS
-- entry the profile is missing. We never overwrite — user's
-- in-profile customisations win, and the vanilla 10 keep SUF's stock
-- (slightly tweaked) values from defaultlayout.lua. The dance covers
-- profile changes / resets too so the entries don't disappear when
-- the user switches profiles.
--
-- Source of truth: whatever the live client populates in
-- _G.RAID_CLASS_COLORS at FrameXML load time (Voljin/PTR realm:
-- patch-B.MPQ → SharedXML/SharedConstants.lua, ~32 entries).
