Walkthrough

The particle system is refactored to consolidate architecture-specific memory-allocation macros into unified public constants while maintaining per-architecture values. Memory allocation retry logic gracefully reduces particle counts on failure, and saturation handling is updated to prevent over-saturation via a min() guard.

Changes

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

• Memory allocation retry logic: Verify loop termination conditions (minimum particle thresholds of 4 for 2D, 10 for 1D) and alignment/halving arithmetic
• Saturation guard: Confirm min() logic correctly prevents palette-derived saturation from being exceeded
• Macro consolidation: Cross-check that all per-architecture constant values align with original definitions and that source count calculation using SOURCEREDUCTIONFACTOR produces equivalent results

Possibly related PRs

• bugfix for very low brightness in PS FX #252: Modifies ColorFromPalette usage and color handling in FXparticleSystem render paths; both PRs touch saturation/color logic in particle rendering.

Poem

🐰 With constants now unified and neat,
Allocation retries make the system complete,
Saturation guards keep the colors just right,
While particles dance in memory's light! 🌟
