// constants — the crop line IS the reference line).

// - Two rifle-scope ticks slide ALONG the fixed line (1-D drag). The owner
|

// rotates the photo until its taped edge sits on the line, then places the
|
||||
// ticks at the tape start/end.
|

// - Declared L = source-space distance between the ticks ÷ px-per-inch —
|

// NOT a projected mask span. Zooming in makes tick placement finer.
