Symbol licences

The symbol sprites in this directory are adapted from the sets below: each source SVG was optimised with svgo (styles inlined, precision reduced), stripped of anything but drawing markup, and combined into one sprite per set. In Mulberry and OpenMoji, people's skin (and in OpenMoji the skin's shadow, as its own skin-tone variants change it) is recoloured: drawn in Unicode's neutral emoji yellow unless the person using the board chooses a skin tone (tools/symbols/people-review.md lists every symbol). The adapted sprites are distributed under the same licence as their source, CC BY-SA 4.0 (https://creativecommons.org/licenses/by-sa/4.0/). They are rebuilt by tools/symbols/build.py in the aac-rs workspace, which also writes three more adaptations of the same sets under the same licence and attribution: the contact sheets tools/symbols/review/*.png (rasterised, each titled with its set's attribution), tools/symbols/mapping-review.md (which quotes the sets' symbol names and BCI-AV glosses) and tools/symbols/people-review.md (which quotes symbol names and emoji annotations).

Mulberry's condition means the symbols can never sit behind a paid tier or a paid hosted library: a product that includes them may charge only for its own added value.
