Type on a path overview
Ride a text run along any curve — native follow, or glyphs deformed with skew and ribbon, plus baseline-shift.
Path effects
The effect field — follow stays native, skew and ribbon shear a height profile, rainbow rotates and bends along the arc.
Placement
Place a run along its path — align distributes the slack, start adds a head-start, and effect="stair" steps live glyphs.
