Brightness-aware elevation tokens (FaiElevation low/medium) applied to cards, sheets and the sidebar active item; gentle hover-lift on Store + Doc cards; a longer, eased sidebar expand using the under-used FaiMotion.slow; and a branded empty state carrying the F∆I delta mark with warmer spacing. Subtle, Linear/Raycast-style — both light and dark themes tuned. Signed-off-by: flemming-it <stefan.a.flemming@googlemail.com>
