-- Per-class catalog of raid cooldowns worth requesting from a teammate.
-- `id` is any rank of the spell; the localized name and icon are resolved
-- from it at runtime, so one entry covers every rank and client locale.
-- `en` is a fallback name used only if the id cannot be resolved.
-- `role` groups/sorts the on-screen bars and gives a sensible ordering.
-- `cd` is the spell's TBC cooldown in seconds, used to show a countdown after
-- the caster uses it (combat-log driven; nil/0 = no timer shown). These are
-- base values — talents/glyphs that shorten them are not accounted for.
