KanjiVG Attribution & ShareAlike Notice
=========================================

PeraNabi Study (formerly Mastermind Japanese) uses adapted stroke-order playback data and kana handwriting
reference patterns derived from KanjiVG.

Upstream work:
KanjiVG: Kanji Vector Graphics
KanjiVG is copyright Ulrich Apel.
Source project: https://github.com/KanjiVG/kanjivg

Adapted bundle license (ShareAlike compliance):
The adapted stroke-path playback bundle, published at
/legal/kanji_stroke_paths.json, and the adapted kana reference-pattern bundle,
published at /vendor/kanjicanvas/ref-patterns-kana.js, are themselves released
under the same Creative Commons Attribution-Share Alike 3.0 (CC BY-SA 3.0)
license as the upstream KanjiVG project, as required by Section 4(b) of
CC BY-SA 3.0 (ShareAlike). No additional restrictions are imposed on these
adapted bundles beyond those in the upstream license.

Changes from upstream:
Path coordinates normalized and re-bundled for in-product stroke-order playback.
Stroke-order information itself is unchanged; only the packaging and coordinate
system have been adapted. For kana handwriting recognition, canonical unsuffixed
SVG paths from KanjiVG commit bd13ffbcc9d85cb86ae98bbbf001d9069220b901 were
flattened and resampled into evenly spaced polylines in KanjiVG's 109x109
coordinate space, then packaged as a Kanji Canvas append bundle.

Credit for reuse of this bundle:

KanjiVG and Ulrich Apel do not endorse PeraNabi Study or this adapted bundle.
The KanjiVG name and the author's name are used here solely for attribution under
CC BY-SA 3.0; their use does not imply sponsorship, affiliation, or approval.

This notice is provided so KanjiVG-derived stroke-order and handwriting-pattern
source attribution is available directly from the site, even though the
