Subject: p79: 夜帧炊烟增强与光晕去叠
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- 炊烟：夜帧烟柱4段向上堆叠(整格32px, alpha 180+75)+暖色外发光(r30)+中性柔光团(r12)；
  烟柱强光像素(夜-昼贡献>=80) 181->1171 (x6.5)，峰值112->173；白天帧逐像素不变。
- 光晕去叠：VillageArt.haloRingLayers 每光源<=2层(内芯+空心外环)，芯环间确定暗隙，半径4->3 tile，
  峰值150->118；光晕重叠面积(夜-昼贡献>=60)中央区 15184->9633 (-36.6%)，全屏 15477->9926 (-35.9%)。
- 回归 P79NightPolishTests(3)；analyze-p78.py 复跑仍 PASS；正午帧与 P78 完全一致=白天零回归。
- Desktop 367/367, Kernel 120/120, digest 953775FA...F7F6C 不变
