- Explicit dark colors on .result-value, .result-label, .result-symbol, .highlighted-value, .highlighted-label
- Include from-unit in results grid (stable definition-order); from-unit tile shows Big(inputValue) and gets is-input-unit dashed-border class
- Shift+click no longer clears highlightedUnitId — fromUnitId and highlightedUnitId are now fully independent states
- Add × dismiss button (aria-label="Remove highlight") to .highlighted-result banner; .highlighted-result gains position:relative
