- KeyboardHints: switch from fixed positioning to absolute, mounted
inside the main content column. The column is now relative-positioned
so the hints overlay centers against the timeline area instead of the
raw viewport (which was off-center because of the sidebars).
- AppFooter: tiny "Built with hubris • <YEAR in roman>" pinned to the
bottom-right corner of the main column. Year is computed at render
time and converted via a small toRoman helper.
