The read
Sill, window, flood. Then a stamp. Never a poster first.
Odile does not open a gate until Beau has a start line that repeats.
Sill
Start line is the sill. Left of the target is a working fade's only honest door. A start at the flag with a hoped-for curve is a costume.
Window
The window is how much curve we allow after the sill. Tight windows for small starts. Open windows for starts that already sit well left. Mixing them is how you kiss the right bank.
Flood
Humidity off the Red adds curve you did not order. If you will not name moisture, Remy marks the log costume and the gate stays down.
