Numbers smoothly count up/down when switching date ranges,
applying filters, or as real-time visitor count changes.

Swap the main site dashboard chart from a bar chart to a line chart
using 21st.dev's line-charts-6 component with dot grid background,
glow shadow, and animated active dots. Add Badge trend indicators
on metric cards using Phosphor icons. All existing features preserved
(annotations, comparison, export, live indicator, interval controls).
New UI primitives: line-charts-6, badge-2, card, button-1, avatar.
Added shadcn-compatible CSS variables and Tailwind color mappings.
