Ear pattern references

Andi manually drew these Illustrator SVGs to match the as-built v1 ear. She explicitly requested that these files and the approved LED fit be kept in the repository on 2026-10-16.

• Combined Outline.svg: registered EVA and expanded front-fabric outlines. This registration was used for the approved fit.
• EVA Outline.svg and Fabric Outline.svg: separate exports, with different origins. Do not overlay their raw coordinates without registration.
• ear-nested-fit_edit.svg: Andi's original inner-loop edit, preserved byte-for-byte. Only its three named inner paths were used; its exported reference outlines are distorted and its package positions are stale.
• v1_ear_asbuilt.jpg: Andi's v1 assembly before the front fabric was attached.

The unitless Illustrator SVG coordinates are points: 25.4/72 mm per unit. The approved, registered millimetre geometry is saved separately in ../ear-fit/curves.svg. These patterns are mechanical references, not PCB Edge.Cuts.

V1 fabric was sandwiched against the frame, without wrapping around it. V2's back fabric is intended to have extra fold-over allowance; that new back cut is not specified here. V1 LED-strip pitch was 6.25 mm between adjacent LED centres, or 12.5 mm per two-LED section.

The original ear design is the MiniStudiios DIY Kitten Ears Pattern by Kittiya Allen, sold by MiniStudioo. The original pattern listing is credited in the repository's README.

Some curves and shapes from the pattern are reused in ESPurr's PCB design files with the creator's permission.

Retain the original-design credit and both links when publishing the derived ear design. The original commercial pattern and third-party artwork are not relicensed by this project. The original PDF says do not redistribute; it, the Illustrator files and superseded automatic traces remain local and ignored.

The final geometry, PDF, placement data and reproduction script are in ../ear-fit/. Earlier generated fit studies have been retired; Git history retains their tooling.
