/reports opens the year: per currency spent so far, a typical month and
this month against typical by today, one lane of category columns per
currency with a dotted typical line and income as dots, what grew next
to the month under the cursor, an honest by-currency table and net worth
lanes weighted by size. Arrows move the month, Enter opens its
transactions, [ ] change the year, m shows the old tables, ?view=month
pins a month with the money flow. Old report URLs still work.
Shared pieces for other pages: Lanes, ledgerQuery for twelve months,
typical-month helpers.
