# snd_mix.c:
#   - paintbuffer clamp loop (per-chunk saturation clip on int32 stereo
#     samples).
#   - BGM stream mix-in loop (paintbuffer[i].left/right += s_rawsamples[]).
#   gcc -O3 auto-vec emits 16-byte SSE/NEON vectors on both; -O2 leaves
#   them scalar.  Combined per-frame saving ~0.8us at 60Hz.
#
# r_alias.c:
#   - R_AliasBlendPoseVerts pose-interpolation lerp inner loop
#     ((pv1->v * blend0 + pv2->v * blend1) >> 22, per alias vertex).
#   Bench at typical numverts=400 shows O2 3.15 ns/vert -> O3 2.22 ns/vert
