Use variant-specific splash icons in mobile app

[juliusmarminge]

Summary

• Route the Expo splash screen image through the active mobile variant config instead of a single shared asset.
• Split splash assets so dev uses its own icon and preview/production share the production splash icon.
• Keep dark-mode splash behavior aligned with the selected variant asset.

Testing

• Not run (PR summary only).
• Confirmed the config change points each variant at the intended splash asset.

Note

Low Risk
Expo config and asset path changes only; no auth, networking, or runtime logic affected.

Overview
The Expo splash screen no longer uses a single shared ./assets/splash-icon.png asset. splashIcon is added to each mobile variant in VARIANT_CONFIG, and the expo-splash-screen plugin reads variant.splashIcon for both light and dark splash images.

Development uses ./assets/splash-icon-dev.png; preview and production both use ./assets/splash-icon-prod.png, matching how variant-specific app icons are already handled.

Note

Use variant-specific splash icons in the mobile app

Updates app.config.ts to add a splashIcon field to the variant config, pointing development builds at splash-icon-dev.png and preview/production builds at splash-icon-prod.png. Both light and dark splash screen images now use the variant-specific asset instead of the previous fixed splash-icon.png.

Approvability

Verdict: Approved

Simple configuration change adding variant-specific splash icons for mobile builds. No runtime logic changes - just different cosmetic assets shown during app launch based on build variant (dev vs prod).
