// curve_popup.h — PURE sheet geometry + dismissal test for the r11 velocity-curve popup
// editor (Wave B, FB1). NO VST3, NO REAPER, NO SWELL/LICE types at the boundary. The mirror
// of overflow_menu: the size-clamp / centering / title-row arithmetic lives here, unit-tested
// at the clamps outside the DAW, while the editor shell draws the wash + sheet through the
// L1 kit and routes clicks (close / curve box / outside-sheet dismiss) via these rects.
//
// THE POPUP (CONTEXT.md §S-VIEW r11). Summoned by the mini curve-preview button, a CENTERED
// SHEET over the Sample face (a 0.50-alpha bg/base wash behind it — lighter than Browse's
// 0.82; a focused sub-editor, not a view change): width clamp(60% of window, 360..520),
// height clamp(55% of window, 260..380). Inside: a ~22px title row ("VELOCITY -> AMP"
// micro-caps left, an 18x18 Close button right) over the full-size curve box filling the
// remainder. The curve box rect here is the BORDER rect — the shell derives the mapping box
// through its ONE curveBoxFromRect formula (the landed inset grammar), so the popup editor
// and the Zone-panel inline editor share coordinates by construction.
