// BenchmarkDaysWeek (mobile_test.go) already covers the OF 7-day view this
// perf fix targets -- see internal/readings/offline.go's offlineLoad, which
// currently re-stacks the calendar layers and re-parses the book table once
// per day inside the loop Days drives. The benchmarks below add the two
// comparisons that let that fix's win be measured: the same view in the
// traditional form (a different, larger embedded calendar layer), and a
// single Day call, the per-day unit of work Days repeats.

// BenchmarkDays7EF is the 7-day view in the traditional (1962) form, whose
// calendar layer is a different embedded file (Tridentine vs Universal).

// Comparing this to BenchmarkDaysWeek/7 shows how much of each day's cost is
// the date-independent setup this fix hoists out.
