Imagine STEM self-hosted font comparison

All four font binaries are unmodified upstream releases. They are bundled with
their original license texts. The application code's license does not replace
any font license. Source URLs, release identifiers, sizes, and SHA-256 hashes
are recorded in SOURCES.json. No runtime CDN or remote font service is used.

IBM 3270
Author/project: Ricardo Banffy and the 3270font contributors.
Source: https://github.com/rbanffy/3270font/tree/v3.0.1
Release: https://github.com/rbanffy/3270font/releases/tag/v3.0.1
Terms: ibm-3270/LICENSE.txt, retained verbatim from the release archive.
The font binary itself explicitly declares SIL Open Font License 1.1 in its
name table; that metadata is transcribed in ibm-3270/EMBEDDED_METADATA.json.
The OFL text is included as ibm-3270/OFL-1.1.txt, with the copyright and license
declaration copied from that font metadata. The separate release
LICENSE.txt permits binary redistribution with its BSD-style terms and named-
glyph notices, and explicitly offers OFL for the FontForge SFD source. Both
upstream statements are retained. The upstream file also states the Debian logo
glyph's CC BY-SA 3.0 / LGPLv3 terms and Canonical's trademark notice.

W95FA
Author: Alina Sava / FontsArena.
Source and author's license statement:
https://fontsarena.com/w95fa-by-alina-sava/
Distribution: https://fontsarena.com/wp-content/uploads/2020/01/W95FA.zip
Terms: w95fa/OFL.txt (SIL Open Font License 1.1), retained verbatim.
The upstream license file has an unfilled template copyright header. We retain
that file rather than invent a replacement grant; the author's page explicitly
identifies Alina Sava and offers this release under the SIL Open Font License
for personal and commercial use. The original readme is also included.
W95FA is a proportional recreation, not a monospaced typeface.

Copyright 2011 The VT323 Project Authors (Peter Hull).
Source: https://github.com/google/fonts/tree/main/ofl/vt323
Terms: vt323/OFL.txt (SIL Open Font License 1.1).

The display-font stack uses a locally available Helvetica Neue, Helvetica, or
Arial through CSS. No proprietary display-font binary is bundled.
