aaronandClaude Opus 5.5 06b656477b docs: move explanations into short module headers
Non-obvious context sits in a brief header at the top of a module, everything else uses single-line comments. niri binds use spawn-sh strings, so neon only overrides the command.

# Nord-style status line built natively, no theme plugin.
# The powerline separators (U+E0B0..U+E0B3) are written as escapes via
# fromJSON: literal private-use glyphs get stripped silently on copy/paste.
# Commas inside #{?...} separate arguments, hence the escaped `#,` below.
