Greptile Summary

This PR refactors svgGeometry.ts to introduce a doubleBrushStroke helper function that replaces manually duplicated SVG path strings, improving maintainability and reducing repetition. The comment explaining the double-brush-stroke anti-aliasing technique is also relocated from stretchy.ts to svgGeometry.ts where the paths are defined.

• Introduces doubleBrushStroke(svgPath) — a one-liner helper that produces `${svgPath} ${svgPath}` — replacing ~14 manual duplications across innerPath() switch cases and the path data object in svgGeometry.ts
• Moves the "Second Brush Stroke" explanation comment from stretchy.ts to svgGeometry.ts, co-locating it with the relevant code and the new helper
• All refactored paths are functionally equivalent — the minor whitespace change (newline → space as separator between the two path copies) is semantically identical in SVG path data
• Pre-existing paths that use a different doubling technique (relative m0 0 after z, e.g. leftharpoondownplus, rightharpoonplus) were correctly left unchanged, as they are not simple string duplications

Confidence Score: 5/5

This PR is safe to merge — it is a pure refactoring with no functional changes to SVG output.

The doubleBrushStroke helper correctly reproduces each original doubled path string. The only semantic difference is whitespace normalization (newline → space between the two copies), which is completely innocuous in SVG path data. All switch cases in innerPath() and all static entries in the path object have been accounted for and verified against the originals.

No files require special attention.
