- One focus treatment for the whole editor: a 1 px accent outline with 1 px offset on :focus-visible.
- Numeric readouts use tabular figures so they do not jitter as values change.
- prefers-reduced-motion turns transitions off and collapses animations to near-zero — and caps iteration count, so a blinking caret settles rather than strobing.
- The canvas viewport reserves its scrollbar gutter, so showing a scrollbar never shifts the design.
