on each ranking proposal card, with x² cost indicator

below the proposal description (supplements chevron ±1)
- Priority Trends chart: SVG line chart showing how proposal scores
evolve over time, with color-coded lines per proposal, end dots,
grid lines, time labels, and a toggleable legend

of simulated history for demo mode
- Orange for upvotes, blue for downvotes (matching rvote.online palette)
