REFACTOR.md — Bite 1: Package Layout

REFACTOR.md — Bite 1: Package Layout

Restructured the single-file justdoit.py into a proper Python package with no behavior changes.

What moved where

Old location (`justdoit.py`)	New location
`BLOCK` dict	`justdoit/fonts/builtin/block.py`
`SLIM` dict	`justdoit/fonts/builtin/slim.py`
`FONTS` registry	`justdoit/fonts/__init__.py`
`COLORS`, `RAINBOW_CYCLE`, `colorize()`	`justdoit/effects/color.py`
`render()`	`justdoit/core/rasterizer.py`
`main()`	`justdoit/cli.py`

New files (stubs / scaffolding)

File	Purpose
`justdoit/core/glyph.py`	Documents the glyph data structure; placeholder for Bite 2 mask abstraction
`justdoit/core/pipeline.py`	Stub documenting the planned stage-chaining architecture
`justdoit/output/terminal.py`	`print_art()` wrapper; first output target in a future multi-target system

Entry points

justdoit.py (root) — thin shim: from justdoit.cli import main; main(). Preserves all existing CLI usage.
justdoit/__init__.py — exports render() and colorize() for programmatic use (from justdoit import render).
skills/ascii_art_generator/main.py — unchanged; from justdoit import render now resolves through the package __init__.
