F1: tomorrow's blocks no longer depend on the battery's level now. Home sizes
a block from the level now (`room()`, `plan_need()` in mode_runs, the leg
sizing in trade_runs) and draws none when there is no room or energy. For a
day that has not started the builders take `ahead=True` (Home never passes
it): a charge is read from the floor, a give from the ceiling. A grid block is
then kept only where `modetrade.chargers()` would charge at the curve's level
when the run starts. The UX-53 gate is unchanged. Today still equals Home; a
give run in the plan with no block (empty battery) has its own sentence
instead of "No charge or give blocks planned".
F2: test_ux54.py part 7 walks the real `_mode_roles()` every 15 minutes
through tomorrow and compares the roles with the tab's blocks (modes on, the
peak gate, part-full batteries), and the control cycle's verdict at 07:00
(modes off).
F3: the curve counts spare solar as trust x max(0, sun - house), stored at
EFF, as `dayplan.plan()` does (10 kWh sun, 2 kWh house, 70 %: 5.32 kWh).
Strings: cycle, no_tomorrow, ahead, no_level, measured; new give_later.
No decision, command, timing or option key changes.
