/* The "your card" line: a measured card, how often it finds a block at the network's hash rate right now, and what its
|
|
electricity costs a day in your currency. One block a second is the target, so the wait is network hashes per second
|
|
over the card's rate. The rates are the bench table's measured numbers (site/miners.html); the watts are the tuned
|
|
draws from the same runs (app.html's Ember table: 5090 226.8 W, 4070 75.6 W; the 9070 XT 202 W from docs/bench-log.md,
|
|
6 October 2026; Apple silicon reports no draw). The currency follows navigator.language (no IP lookup); the switch saves
|
|
a choice in localStorage igneum-currency; the tariff is the public table's default for that region or currency, so the
|
|
cost is arithmetic from a typical price, never a promise (currency-21, 7 October 2026). Reads /api/live every 15 s. */
