minWidthPx constant
double
const minWidthPx
Pixel floor for the available paint area, mirroring orca's MIN_PANE_FIT_WIDTH_PX (48) / MIN_PANE_FIT_HEIGHT_PX (24). With tiny fonts a container can satisfy the 8×4 cell floor while still being a near-zero transition frame; this catches that case too (double guard, pixels + cells).
Implementation
static const double minWidthPx = 48;
