- **Visual Effects**: Upgraded line clear particles to use the game's block texture instead of simple circles, matching the reference web game's aesthetic.
- **Particle Physics**: Tuned particle velocity, gravity, and fade rates for a more dynamic explosion effect.
- **Rendering Integration**: Updated [main.cpp](cci:7://file:///d:/Sites/Work/tetris/src/main.cpp:0:0-0:0) and `GameRenderer` to pass the block texture to the effect system and correctly trigger animations upon line completion.
- **Menu UI**: Fixed [MenuState](cci:1://file:///d:/Sites/Work/tetris/src/states/MenuState.cpp:19:0-19:55) layout calculations to use fixed logical dimensions (1200x1000), ensuring consistent centering and alignment of the logo, buttons, and settings icon across different window sizes.
- **Code Cleanup**: Refactored `PlayingState` to delegate effect triggering to the rendering layer where correct screen coordinates are available.
Add an in-game exit confirmation modal for Playing state: ESC opens modal and pauses the game; YES resets and returns to Menu; NO hides modal and resumes.
Draw a full-window translucent dim background (reset viewport) so overlay covers any window size / fullscreen.
Use PressStart2P (pixel P2) font for all modal text and center title/body/button labels using measured text widths.
Add FontAtlas::measure(...) to accurately measure text sizes (used for proper centering).
Ensure popup rendering and mouse hit-testing use the same logical/content-local coordinate math so visuals and clicks align.
Add keyboard shortcuts for modal (Enter = confirm, Esc = cancel) and suppress other gameplay input while modal is active.
Add helper scripts for debug build+run: build-debug-and-run.ps1 and build-debug-and-run.bat.
Minor fixes to related rendering & state wiring; verified Debug build completes and modal behavior in runtime.
