Implement Amber/Nord/High Contrast theme presets with XDG user-scoped persistence and reduced motion toggle. Covers TPH-10 and preference integration with TPH-2. - preferences.py: safe load/save with XDG_CONFIG_HOME/fenris/preferences.json - themes.py: three Textual Theme objects with graph colour roles - TUI: t cycles presets, m toggles reduced motion, both persist across restart - Status composition receives reduced_motion from preferences - 56 new tests covering persistence, themes, TUI integration, CLI isolation - All 590 existing tests continue to pass

"""Fenris theme presets (issue #80).
|
|
|
|
Three accessible colour presets: Amber (default), Nord, and High Contrast.
|
|
Themes style chrome, borders, accents, muted text, and graph roles;
|
|
status semantic colours/glyphs/text always win.
|
|
|
|
Theme roles for graph rendering expose distinct colours per preset so
|
|
the bar graph can reflect the user's visual preference without depending
|
|
on graph-ticket completion.
|
|
|
|
Criteria: TPH-10, AC80-1, AC80-5.
