Shows the next 90 days as a horizontal bar chart above the conference
list. A greedy interval-colouring algorithm assigns each conference to a
lane so overlapping conferences appear in separate rows. Lane colour
cycles through a fixed palette so simultaneous events are easy to tell
apart. Month boundary markers and a red today-line provide orientation.
All position maths happens in build_conference_timeline() in Python;
the Jinja template is pure rendering.
