Response for usage statistics (2-tier daily limits)
Usage breakdown with percentage, used, and limit.
window says what period used and limit are measured over. It defaults to "day" because every consumer tier is rationed daily; a school seat is rationed by the WEEK, and a screen that prints a weekly figure under the word "today" is simply wrong. resets_on is the last date of that window.
resets_at is the exact INSTANT it next rolls over, in UTC, so the client can print it on the reader's own clock. The daily counters turn over at midnight New York and a school week turns over at midnight in the school's zone — neither is the reader's midnight, so "resets at midnight" was telling a learner in Berlin something untrue by six hours.
