The card's depth always rode billed tokens; now a Sessions/Steps toggle
in the card's top-right corner (default steps) picks the metric, and the
day tooltip gains a steps line beside the sessions count. Sessions and
steps shape the window's days on different spans - one long session
drops a step a day, another day stacks a run - so the join tracks an
independent window maximum per metric and never scales one off the
other's peak. A billed day with no settled step (a legal wire shape)
stays gray under steps yet still tips and pins. The toggle rides the
shared lc-gran idiom inside a lc-heat-ctl wrapper - one auto margin for
the hint text plus the group - and specs cover both scales plus the
panel-level switch.
