9//! workspace can owe at all (private storage past 1 GB). Free workspaces
10//! have no on-demand compute: the trial and g1t's pools pay for it.
11//! - **Paid, first month**: `LIMIT_PAID_START_MICROS` ($100) while the plan
12//! is in its first billing cycle.
13//! - **Paid, after**: twice what it has paid g1t once payments clear
14//! (`SETTLE_DAYS`), never less than the starting ceiling; after three
15//! steady months it follows the monthly spend, up to $10,000.
16//! - **Reviewed**: a ceiling g1t staff set by hand.
Spend caps: a monthly budget for comped workspaces and a daily breaker on what g1t pays17//! - **Internal**: g1t's own workspaces, with none here: what their work
