v0.19.2 - Experimental Windows release

TrueTrack 0.19.2 — Welcome and clearer guidance

• Minimal welcome screen with an optional preferred-crosshair selector and preview.
• More visible default cyan crosshair with a dark outline and open centre. Saved choices and existing measurement snapshots are retained.
• Large, centred circle-test instructions with fade-in, click-to-start and fade-out before countdown and recording.
• Clearly explains 30 clockwise and 30 counterclockwise turns, natural movement and the pause between directions.
• 32–34 pixel progress bars with completed counts and percentages.
• Red flick bullseyes; precision targets remain green.
• Updated documentation and screenshots.

Update through History / updates, or extract the entire Windows ZIP and run TrueTrack/TrueTrack.exe. Measurements, profile data, routines and saved crosshair preferences are retained. No driver is installed and no profile is activated by the update.

Validation: 443 automated checks, visual inspection of the welcome/circle/target screens and a packaged-update preservation check. Experimental, unsigned Windows x64 release. Full questionnaire onboarding, research data collection and global crosshair overlays are not implemented.
