Summary

Adds a post-processing script for analog print effects, transforming clean AI-generated images into physically printed artifacts. This is the single highest-leverage quality improvement — it works regardless of which image generation provider is used.

Changes

  • nous-branding/scripts/postprocess.py — New Python script (Pillow + numpy) with 14 analog-print effects organized into three processing modes (imprint, nous, standard).
  • nous-branding/SKILL.md — New "Post-Processing" section documenting modes, intensity calibration, and integration workflow.

Related Issue

Closes #33

Type of Change

  • ✨ New feature
  • 🐛 Bug fix
  • ♻️ Refactor
  • 📝 Documentation (also includes doc updates)
  • 🧪 Test
  • 🔧 CI/CD

Checklist

  • Script passes Python syntax check (ast.parse)
  • SKILL.md updated with usage documentation
  • MIT attribution to plntrprotocol/nous-branding in script header
  • Three processing modes documented with intensity calibration

Notes for Reviewers

Adapted from the approach in plntrprotocol/nous-branding's MIT-licensed postprocess.py. Our implementation is independent code sharing the same algorithmic goals — attribution is in the script header. The 14 effects mirror their --mode imprint pipeline, which is the community-corrected target for the Nous aesthetic.

Adds scripts/postprocess.py with 14 analog-print degradation effects
(warm grade, CRT scanlines, film grain, Bayer dither, vignette,
chromatic aberration, screen print texture, paper fiber, ink bleed,
palette compression, xerox threshold, registration offset, plate
wobble, print scuffs) and corresponding SKILL.md documentation.

Adapted from the approach pioneered by plntrprotocol/nous-branding
(MIT) — same goals, independent implementation.

Supports three modes: imprint (full 14 effects), nous (9 base effects),
standard (6 light effects). Intensity calibration from 0.45 to 0.8+.

Closes #33
