beautify-decoration

# beautify-decoration (v1) A repo-specific iteration loop for visually redesigning a decoration in `ascii-agents`. Follow this when the user says "beautify X" or "make Y look better" — it short-circuits several rebuild traps and visual-design dead ends that aren't obvious from the codebase alone. ## When to use - Redesigning an existing decoration sprite (pantry, lounge, meeting, cubicle decor) - Adding a new fixture (pendant lamp, water cooler, chalkboard, etc.) - User says "items look too small / don't read like X / blend together" - After making sprite edits and "I don't see any change" ## The visual-iteration loop ``` 1. Edit sprite OR layout ↓ 2. cargo build --release --example snapshot ↓ 3. ./target/release/examples/snapshot --cols 192 --rows 80 /tmp/snap.png ↓ 4. .venv/bin/python3 scripts/crop-snapshot.py /tmp/snap.png --scale 3 -q <quadrant> ↓ 5. Read the cropped PNG → self-critique → back to step 1 ↓ 6. When happy, send to user with SendUserFile and short caption ↓ 7. cargo build --release --workspace ← rebuild the LIVE binary too ↓ 8. Commit with iteration history (which designs were tried, why rejected) ``` The user is the final judge of "does it look like a fridge / coffee machine / etc." — but you should self-critique before sending. Three iterations of self-critique before bothering the user. **Step 7 is mandatory.** `cargo build --release --example snapshot` does NOT rebuild the main binary.
