Changelog

[Unreleased]

Controls::Edit — EDIT control customization with dark theme matching Controls::Button:
- Custom WinProc with WM_ERASEBKGND (dark background), WM_PAINT (flat border), WM_NCPAINT passthrough
- Subclass / Unsubclass API, removes WS_EX_CLIENTEDGE
- AutoHideScrollbar — hides vertical scrollbar when text fits the client area
- Applied to input fields in PromptDialogProc and MessageBoxDialogProc2
Controls::Tooltip — Public reusable tooltip popup control:
- Create, SetText, SetPosition, Destroy API
- Dark-themed round-cornered window (RoundRect border + clip region for text)
CtrlDraw::DrawFrame — Utility to draw a flat (non-rounded) rectangle frame with 1px border
DynamicColorPicker — New non-blocking dynamic color picker dialog:
- HSL colour wheel (2D canvas: saturation × lightness)
- Hue strip + alpha strip sliders
- RGBA / HSL / HEX numeric input fields
- Old vs new color preview
- Screen color picker (eyedropper tool)
- Runs in a separate thread; uses Controls::Button::Subclass and Controls::Edit::Subclass
- Factory function: CreateDynamicColorPicker(title, r, g, b, a, hParent)

Dark theme consistency — All hardcoded RGB() colors in PromptDialogProc, MessageBoxDialogProc2, DynamicProgressBar, and DynamicSlider replaced with theme.* colors
PromptDialogProc — Now calls Controls::InitWindowColor, Controls::Button::Subclass on OK/Cancel buttons, and Controls::Edit::Subclass on the input field. All color handlers (WM_CTLCOLOREDIT, WM_CTLCOLORSTATIC, WM_CTLCOLORBTN) use theme colors.
MessageBoxDialogProc2 — Added WM_CTLCOLORSTATIC handler (for ES_READONLY EDIT), all color handlers use theme colors. Controls::Edit::Subclass applied.
DynamicSlider — Removed static Value: label; current value shown as a tooltip thumb when dragging. Slider track moved up to fill the space.
Build flags — Added -ldwmapi linker flag (for DwmSetWindowAttribute)
