Player interaction ripples: vertex shader adds radial damped-sine displacement centered on player position, fragment shader adds matching normal perturbation for specular highlights. Player XY packed into shadowParams.zw, ripple strength into fogParams.w. Separate 1x render pass for water when MSAA is active to avoid MSAA-induced darkening — water renders after main pass resolves, using the resolved swapchain image and depth resolve target. Water 1x framebuffers rebuilt on swapchain recreate (window resize).
