-- CoAClassColors.lua
--
-- Forwards the live client's RAID_CLASS_COLORS palette into
-- _G.CUSTOM_CLASS_COLORS so Omen renders Conquest-of-Azeroth class
-- bars correctly when the !ClassColors addon is loaded.
--
-- Background
-- ----------
-- The CoA Voljin client (and the Ascension classic+ client) ship
-- 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, …). Omen.lua:1629 reads
-- RAID_CLASS_COLORS directly, so the unmodified addon already paints
-- CoA classes with the realm-canonical palette.
--
-- The exception is the !ClassColors path. !ClassColors injects a
-- separate _G.CUSTOM_CLASS_COLORS table, populated from its own
-- (vanilla-10-only) defaults plus user overrides. Omen prefers
-- CUSTOM_CLASS_COLORS over RAID_CLASS_COLORS when present (Omen.lua
-- :914-917, options at :2828), so on a !ClassColors-equipped client
-- the 22 CoA tokens silently fall through and bars revert to the
-- generic dbBar.BarColor.
--
-- Strategy
-- --------
-- If CUSTOM_CLASS_COLORS exists at file-load time (i.e. !ClassColors
-- already loaded — Omen.toc declares it as an OptionalDep, so it loads
-- first when installed), copy any RAID_CLASS_COLORS entry that
-- CUSTOM_CLASS_COLORS is missing. Never overwrite — !ClassColors user
-- preferences and any other addon's earlier write win.
--
-- We deliberately don't touch RAID_CLASS_COLORS itself: the client
-- already populates it, and any value we'd choose here would be a
-- guess relative to the realm-authoritative palette in
-- SharedConstants.lua.
--
-- Source of truth: _G.RAID_CLASS_COLORS at FrameXML load time
-- (Voljin/PTR realm: patch-B.MPQ → SharedXML/SharedConstants.lua).
