+
+// how the Live2D draw filtering works
+// ------------------------------------
+// SDVX draws its Live2D characters with a small, fixed set of pixel and
+// vertex shaders. to skip those draws (and save GPU) we have to recognise them at
+// the exact moment the game issues a draw call. the d3d9 device hooks feed three
+// kinds of events into this module:
+//
+//   1. shader creation  (on_create_pixel_shader / on_create_vertex_shader)
+//        the game compiles its shaders once at load. we can't trust the shader
+//        *object pointer* to identify a shader (it's just a heap address that
+//        varies per run and can be recycled), so instead we hash the shader's
+//        D3D9 *bytecode* - that fingerprint is stable across runs because the
+//        game ships the same shaders. if the hash matches a known Live2D shader
+//        we remember that object pointer in g_live2d_shaders.
+//
+//   2. shader binding   (on_set_pixel_shader / on_set_vertex_shader)
+//        whenever the game binds a shader we look it up in that set once and cache
+//        the yes/no answer in g_cur_ps_is_live2d / g_cur_vs_is_live2d. binds happen
+//        far less often than draws, so this is where the lookup cost lives.
+//
+//   3. draw call        (should_skip_draw, called from every Draw* hook)
+//        the per-draw question "is this a Live2D draw?" is then just reading those
+//        two cached bools - no hashing, no map lookups. if the skip is currently
+//        active (see graphics_sdvx_live2d_should_skip) and either bound shader is
+//        Live2D, the Draw* hook drops the call instead of forwarding it.
+//
+// everything is gated on the feature being enabled (mode != Off); when it's Off
+// every entry point is a single predicted-not-taken branch. d3d9 rendering for a
+// device is single-threaded, so none of this state needs locking.
