ZacharyZhang-NY c474a3eb33 Canvas · Tools: select, move and snap, resize, draw, pen, text, brush ...

ToolLayer lies over an InfiniteCanvas and carries its tools. Select
takes the topmost shape a press reaches, Shift adds or drops one, a
drag moves the selection and snaps its nearest edge or middle to
another shape's within reach, a handle resizes it, Shift keeping a
corner's shape, and a drag on empty space draws a SelectionBox that
takes what lies wholly inside. The shape tools draw by a drag toward
any corner, Shift keeping them square; the pen adds a point per press
and a double press ends the path; text drops a line where pressed; the
brush strokes a path its width. A drag may end in the layer or out of
it; each gesture ends once and asks the owner. SelectionBox,
TransformHandles and SnapIndicator draw the marks.

ToolPalette picks a tool from icons named in tips; BrushSettings sets a
brush's width and hue; HistoryPanel lists the steps done, the undone
ones quiet, and takes the drawing to a step on Enter or a double press.

The model changes: lines and arrows end at a named corner, so they run
either way, and paths carry their width. Three Lucide icons: hexagon,
slash and move-up-right.
