---[[ librange ]]--
--- A thin wrapper over ClassicAPI's UnitInRange: a fixed 40y healing-range
--- check computed C-side from unit positions, valid for any unit. There is
--- no cache or scan loop -- the check is cheap enough to run per query,
--- which also sidesteps the staleness a cached scan hit on zone changes and
--- roster re-indexing.
---
---  librange:UnitInSpellRange(unit)
---    Returns `1` if the unit is within range, `nil` otherwise.
