bgHamNoSysUnicode — Hamburg HamNoSys 4.0 Unicode font
======================================================

This directory hosts the Hamburg HamNoSys 4.0 Unicode font
(`bgHamNoSysUnicode.ttf`), used by the Bridgn/Kozha contribute page to
render HamNoSys phonetic notation glyphs at their intended visual
fidelity (§ 5 of the HamNoSys 4.0 manual).

Provenance
----------
- Maintainer: Institute of German Sign Language and Communication of the
  Deaf (IDGS), University of Hamburg.
- Upstream: https://www.sign-lang.uni-hamburg.de/dgs-korpus/tools/hamnosys
  (also distributed via the CTAN ``hamnosys`` LaTeX package,
  https://ctan.org/pkg/hamnosys).
- Authors: Thomas Hanke, Marc Schulder, et al. (IDGS/DGS-Korpus project).

The font is distributed by IDGS for academic, research, and
notation-tool use. When redistributing the binary alongside Kozha,
retain this file and the original IDGS license bundled with the font
(ship it as `bgHamNoSysUnicode.LICENSE.orig.txt` alongside the `.ttf`).
This file is a pointer — the binding license terms are the IDGS terms
shipped with the font itself.

Credit
------
If you use this font, credit IDGS (University of Hamburg) per the
project's README ("Credits → Notation System"). See:

Why we load it locally
----------------------
Per the contribute-page redesign (prompts/prompt-contrib-7.md §2), the
font must be loaded via a local `@font-face` declaration rather than
depending on a CDN. The declaration lives in `/public/contribute.css`.
If the `.ttf` is absent, browsers fall back to the system stack and the
HamNoSys codepoints render as replacement boxes — the UI still works,
it just isn't pretty.
