The courtyard with two different privacy problems

Do not let one good July afternoon approve a permanent object.

This is the annual vote. The same proposed screen, awning, pergola, move or planting change is held fixed while the engine re-runs the property in winter, spring, summer and autumn.

The hour is intentionally held constant. This isolates seasonal geometry instead of letting a different clock time flatter the proposal.

The year, in one line

Everything below is about a change. Before that, it is worth knowing what the place already does — the hours it is open, month by month, on one page you can put on a fridge.

Before a permanent change gets to win

Make January, April, July and October vote on it.

These are the exact same proposed objects re-run through the engine in four seasons. A summer fix that steals winter sun cannot hide inside one July score.
