Licenses & Attribution

# Third-party notices

This file is the single source for the attribution this site owes. `/licenses`
renders it verbatim at build time — a hand-written second copy on that page is
exactly the drift that eventually breaks a notice condition.

**The test for inclusion is whether the bytes leave our machine**, not whether a
package appears in `package.json`. This is a static site: the HTML, the CSS,
the client-side JavaScript runtime and the font files are all downloaded by
every visitor, so everything in them is redistributed and gets a notice below.
Tooling that only ever runs on our own machines is listed at the end under
"Deliberately not listed" — because "considered it and excluded it" and "forgot
about it" look identical in a file like this.

## Fonts (self-hosted, delivered to every visitor)

The three typefaces are downloaded at build time by `next/font/google` and
served from this site's own origin (`/_next/static/media/*.woff2`). Self-hosting
is what makes these notices mandatory: the SIL Open Font License requires its
text to travel with the font files.

`scheduler` and `styled-jsx` are not direct dependencies — they arrive with
React and Next respectively and are bundled into the client runtime, which is
what puts them here.

## Deliberately not listed

These run only during development and deployment. Their bytes never reach a
visitor, so no notice is owed — but the decision is recorded rather than left
looking like an omission:

- **tailwindcss** and **@tailwindcss/postcss** — generate our stylesheet at
  build time. The CSS that ships is our own output, not their code. (MIT.)
- **wrangler** — uploads the build; runs in CI.
- **eslint**, **prettier** and their plugins — never leave the repo.
- **vitest**, **@playwright/test**, **@axe-core/playwright** — test tooling.

If a dependency is ever added that ships to the browser, it belongs in the
table above. The check is always the same one: do these bytes leave our machine?

SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
-----------------------------------------------------------

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.

The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded, 
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.

DEFINITIONS
"Font Software" refers to the set of files released by the Copyright
Holder(s) under this license and clearly marked as such. This may
include source files, build scripts and documentation.

"Reserved Font Name" refers to any names specified as such after the
copyright statement(s).

"Original Version" refers to the collection of Font Software components as
distributed by the Copyright Holder(s).

"Modified Version" refers to any derivative made by adding to, deleting,
or substituting -- in part or in whole -- any of the components of the
Original Version, by changing formats or by porting the Font Software to a
new environment.

"Author" refers to any designer, engineer, programmer, technical
writer or other person who contributed to the Font Software.

PERMISSION & CONDITIONS
Permission is hereby granted, free of charge, to any person obtaining
a copy of the Font Software, to use, study, copy, merge, embed, modify,
redistribute, and sell modified and unmodified copies of the Font
Software, subject to the following conditions:

1) Neither the Font Software nor any of its individual components,
in Original or Modified Versions, may be sold by itself.

2) Original or Modified Versions of the Font Software may be bundled,
redistributed and/or sold with any software, provided that each copy
contains the above copyright notice and this license. These can be
included either as stand-alone text files, human-readable headers or
in the appropriate machine-readable metadata fields within text or
binary files as long as those fields can be easily viewed by the user.

3) No Modified Version of the Font Software may use the Reserved Font
Name(s) unless explicit written permission is granted by the corresponding
Copyright Holder. This restriction only applies to the primary font name as
presented to the users.

4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
Software shall not be used to promote, endorse or advertise any
Modified Version, except to acknowledge the contribution(s) of the
Copyright Holder(s) and the Author(s) or with their explicit written
permission.

5) The Font Software, modified or unmodified, in part or in whole,
must be distributed entirely under this license, and must not be
distributed under any other license. The requirement for fonts to
remain under this license does not apply to any document created
using the Font Software.

TERMINATION
This license becomes null and void if any of the above conditions are
not met.

DISCLAIMER
