Bundled font licenses & attribution

@openmaic/renderer does not embed any font binaries. fonts.css only declares @font-face rules whose src points at self-hosted woff2 files on object storage (https://file.maic.chat/fonts/<name>.woff2). Serving those faces is a form of redistribution, so each face below must be cleared for redistribution and attributed here. This file is the font attribution/clearance record; it is separate from the package's own LICENSE (MIT), which does not cover the fonts.

The importer does not remap fonts: it passes each slide's original font-family names through unchanged. A name only renders in one of the faces below if it matches; otherwise the browser falls back. This list mirrors fonts.config.mjs.

✅ = free to redistribute (bundle/embed/serve) as long as its conditions are met (notice/license travels with it; not sold on its own). The four OFL faces are OFL 1.1; ZcoolHappy is permanently free for everyone to use with the conditions noted below.

ZcoolHappy — note

Permanently free for everyone to use, including commercial use, per ZCOOL's statement (font-licenses/ZcoolHappy-LICENSE.txt). Conditions: keep the original font name unchanged, do not resell the font as a standalone commodity, and retain the designers' attribution. Serving it from our CDN as part of this free package meets those conditions.

SIL Open Font License 1.1 (the 4 OFL faces above)

OFL §2 requires the copyright notice + this license to accompany every redistributed copy. The full OFL 1.1 text and the four per-face copyright lines are bundled at font-licenses/OFL.txt.

WenDingPLKaiTi (AR PL KaitiM GB) — Arphic Public License 1999

The WenDingPLKaiTi family served here is a WOFF2 conversion / distribution of AR PL KaitiM GB (文鼎 PL 简中楷) licensed under the Arphic Public License. AR PL KaitiM GB is one of the four fonts Arphic Technology released in 1999 under that license — an FSF-recognized copyleft free-software license that explicitly permits commercial use and verbatim redistribution ("You may copy and distribute verbatim copies of this Font in any medium, without restriction, provided that you retain this license file (ARPHICPL.TXT) unaltered in all copies"). Arphic reconfirmed in 2022 that these four 1999 faces remain free for commercial use (distinct from the 2010 non-commercial license).

Identity verified from the woff2's embedded name table (so the WenDingPLKaiTi ⇄ AR PL KaitiM GB correspondence is provable, not asserted):

nameID 1/4 Family/Full   : AR PL KaitiM GB
nameID 0   Copyright      : (c) Copyright 1994-1999, Arphic Technology Co., Ltd.
nameID 7   Trademark      : Arphic is a registered trademark of Arphic Technology Co., Ltd.
nameID 8/9 Manufacturer/Designer : Arphic Technology Co., Ltd.
nameID 11  Vendor URL     : http://www.arphic.com.tw
nameID 13  License         : ARPHIC PUBLIC LICENSE (full text embedded)

(Reproduce with fc-scan or python -m fontTools.ttx -t name <file>.)

Modification notice (Arphic PL §2.a): the only changes from the original AR PL KaitiM GB are (1) format conversion from TrueType to WOFF2 and (2) the exposed font-family name WenDingPLKaiTi. No glyphs were modified. The verbatim license is bundled at font-licenses/ARPHIC-PL.txt and must be kept unaltered alongside the served font.

Removed faces

Faces previously bundled but dropped from the whitelist because their redistribution terms are not clearly permissive:

• The FangZheng family (Hei / Kai / ShuSong / FangSong), MiSans, DeYiHei and several display faces — commercially licensed.
• AlibabaPuHuiTi (阿里巴巴普惠体) — free for commercial use, but its license grants no explicit redistribution/re-host right (unlike OFL), so it was dropped to keep redistribution unambiguous.

If any are reinstated, add a cleared license entry above first.
