-- TotemBar - core/pulsedata.lua
-- Pulse metadata per totem name (PURE data, no WoW API). Drives the pulse
-- progress bar in ui.lua. Totems absent from PULSE_DATA get NO pulse bar
-- (better no info than invented info) - notably Searing Totem (irregular
-- attack cadence, not a fixed pulse), Grounding (event-consumed) and every
-- aura totem (continuous aura, no verified pulse mechanic).
--
-- Values are server-dump-derived (TWoW server dump, snapshot 2024-07,
-- patch_1172 branch; tw_world.sql + SpellAuras.cpp:8647-8714), not book
-- values - source="server" records that provenance. verified=false stays
-- reserved for IN-GAME confirmation: /tb pulsecal (core/pulsecal.lua)
-- captures the real timings; once measured in-game, update the value AND
-- flip verified=true.
--
-- firstTick: "immediate" means the aura's periodic tick fires at t=0 (the
-- totem is on SpellAuras.cpp's CalculatePeriodic exception list);
-- "delayed" means the first tick lands only after one full amplitude has
-- elapsed. NOTE: the pulseRatio math is identical either way - the bar
-- reaches 1.0 at every tick instant, including the t=0 wrap for
-- "immediate" totems - so firstTick is currently documentative only (no
-- consumer branches on it yet). Kept for future use, e.g. a distinct
-- wave/flash at t=0 for "immediate" totems.
