LAVI_BLOOMZ  -  lightweight atmospheric shader for weak GPUs (Intel HD 4000 target)
Target: Minecraft 26.1.2 + Iris 1.10.9

INSTALL
  Drop Lavi_bloomz.zip (unextracted) into  .minecraft/shaderpacks/
  Video Settings > Shader Packs > Lavi_bloomz. Pick a profile on the first page.

WHAT IT DOES (all cheap)
  - Terrain lighting: sky-tinted ambient, warm torchlight, sun/moon direct light
  - Shadows: one 768px shadow map, warped to favour nearby pixels, 5 taps, fades out at distance
  - Fog: per-vertex, blends into the sky gradient; render-edge fade hides chunk pop-in
  - Sky: gradient + sunrise/sunset glow built from vanilla sky/fog colours
  - Water: 3 analytic ripples, fresnel sky reflection, sun glitter (no SSR, no extra pass)
  - Wind: leaves and plants sway slightly (vertex only)
  - Bloom: ONE post pass, 5 taps from the GPU mip chain, plus soft S-curve and saturation

PROFILES
  POTATO      shadows 768 / 48 blocks (default)
  POTATO_MIN  shadows off - best FPS
  BALANCED    shadows 1024 / 64 blocks

IF SOMETHING LOOKS WRONG
  Striped shadows ......... Shadows > Shadow Bias up (1.5 or 2.0)
  Shadows detached ........ Shadow Bias down (0.75)
  Bloom too hazy .......... Bloom Strength down or Threshold up
  Fog too strong/weak ..... Fog Amount
  Compile error ........... send me the exact line from the Iris log (latest.log)

FPS TIPS FOR HD 4000
  Render distance 6-8, Sodium installed, clouds Fast, 1280x720 or lower window,
  Smooth Lighting on is fine. Use POTATO_MIN if shadows still cost too much.
