- Cards (featured + gallery): hover adds -translate-y-1 + shadow-lg for
subtle lift-off-surface effect
- Homepage sections: replace hard border-b with gradient-fade dividers
that taper to transparent at edges
- Resistor button section: tighten vertical padding (py-10 → py-6)
- Notebook editor: cell spacing increased (space-y-0 → space-y-3),
add-cell button slides up on hover instead of abrupt opacity flash,
status bar gets more breathing room and lighter text
