-The tooltip scan is unavoidable because ClassicAPI does not expose the reagent
-requirements needed for this action-button feature. Item counting itself is now
-ClassicAPI-first indirectly through the shared `ShaguTweaks.GetItemCount`
-helper. Previously an `OnUpdate` ran permanently and all 120 action slots were
-rescanned after every bag event.
+ClassicAPI now resolves action slots and macros to spell IDs, exposes spell
+reagent item IDs directly, and provides direct inventory counts. The module no
+longer scans action tooltips or parses localized reagent text.
 
-Now the frame sleeps while idle. Action-layout events request a one-frame
-tooltip rescan; `BAG_UPDATE` only refreshes counts for reagents already known.

+The frame still sleeps while idle. Action-layout or macro events rebuild the

-Fixed a broken `create_hash` call that omitted the `prefix` argument and
-shifted all remaining parameters. This could feed a number into string
-operations during map overlay processing.
+The old hand-maintained Vanilla and Turtle overlay tables were removed.
+ClassicAPI now reads `WorldMapOverlay.dbc` from the active client and returns
+the exact unexplored overlays and resolved tile layout, including custom
+Turtle-like zones.
 
-The module no longer manually replaces `WorldMapFrame_Update`. A pre-hook
-clears overlay textures and a post-hook adds the reveal layer while preserving
-the native/Turtle updater.
+The module keeps Blizzard's normal explored-map rendering untouched and adds
+only the unexplored reveal layer in a safe post-hook of
+`WorldMapFrame_Update`. Exploration markers use ClassicAPI hit rectangles and
+localized area names when available.
 
-Internal overlay state is now anchored explicitly on `WorldMapFrame` instead
-of relying on the implicit global `this` value.
-
-Turtle WoW 1.18.1 custom map overlay data from upstream is preserved.
+This removes the large static map database and the manual tile-grid logic while
+making the reveal data follow the installed client's actual maps.
