Live price charts and a watchlist

Two additions aimed at making the Markets side of the site actually useful to come back to, not just a one-time lookup.

Price charts. Every coin page now has a price history chart: tap 24H, 7D, 30D, 90D, 1Y, or MAX to change the range, and hover to see the exact price at a point in time. Alongside the chart, coin pages now also show 24h high/low, all-time high/low, market cap rank, fully diluted valuation, and a circulating-vs-max-supply bar.

Watchlist. Click the star (☆) next to any coin (on its own page or in the markets table) to add it to your watchlist. No account needed: it’s saved in your browser, so it’s private to you and persists between visits on the same device. Visit /watchlist to see live prices for everything you’ve starred, or filter the markets table down to just your watchlist with the ”★ Watchlist” button.

Since it’s stored locally rather than tied to an account, it won’t follow you to a different browser or device: that’s a deliberate tradeoff to avoid requiring sign-up for something this lightweight.
