-# Code block color scheme sources
-
-Canonical sources for the schemes in
-`Modules/Notifications/Sidebar/Chat/Content/CodeColors.qml`.
-
-Rules:
-
-- Verify one scheme at a time, in order.
-- HSL/RGB values from the specs are converted with a Python script,
-  never by hand:
-  `python3 -c "import colorsys; r,g,b = colorsys.hls_to_rgb(h/360, l/100, s/100); print('#%02x%02x%02x' % tuple(round(c*255) for c in (r,g,b)))"`
-  (HLS in Python is h, l, s — note the order.)
-- Check the box only after the QML is fixed and verified against the spec.
