Apply a codebase-wide comment audit against the comment conventions:
split banned semicolons and multi-sentence lines into one sentence per
line, cut cross-file and history narration, trim file-top headers to a
single purpose line, and drop verbosity that did not earn its place.
Prose docs (CLAUDE.md, install.md) get the same one-sentence-per-line
and no-semicolon treatment.
Narrow the terminal tools excluded from Stylix to nvim alone. nvim keeps
its dedicated gbprod/nord.nvim colorscheme, which is richer than the
base16 mapping Stylix would apply.
tmux and fish are now Stylix-managed. Drop the hand-written Nord colours
from the tmux status bar so Stylix themes the status and pane styles,
keeping the minimal layout (session name plus window list) reapplied
after Stylix so it still wins.
Configure tmux through home-manager's programs.tmux: the settings it exposes
as options (prefix, keyMode, mouse, baseIndex, clock24, escapeTime,
historyLimit, terminal) are set as options, and every setting it has no option
for is read verbatim from modules/tmux/extra.conf. No tmux plugin manager is
used. The generated config is behaviourally identical to the reference, verified
by parsing it with a live tmux binary.
