- fit.py: centre each glyph and scale it so its furthest ink sits at INK_RADIUS = 340px, compensating the unscaled stroke width - style.py: INK_RADIUS plus INK_RADIUS_DP for vector-drawable consumers - labels.py/_label_widths.py: LABELS registry; names start with a capital, ASCII letters only, <= 10 chars, <= 522 wide in the Pixel launcher font - drop centre_offset, safe_box_overflow and the CLI safe-box warning - add prompt-bubble (sufler) and camera (macro_cam) glyphs and apps Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_012kQ5PCKqBHAkAVkPSvp6dk
