Qetch: Time Series Querying with Expressive Sketches

Summary: Canvas-based, sketch-first time-series querying with a top-down design, not tied to DTW/ED-style sketches. Scale-free matching tolerates rough user sketches, supports annotations (span, amplitude, offset, repetition/negation), and multi-series, time-ordered queries via horizontal sketch placement, keeping the canvas as the primary query surface.
