Turns the newly-added issues in docs/FEEDBACK.md into four more
self-contained tickets: always-interactive map with a recenter
button, Route Planner's Null Island centering bug, HUD reflow-on-hide,
and title-driven HUD sizing. Sequenced FB-08 before FB-09 since both
rework the same HUD layout files.
Turns docs/FEEDBACK.md into five self-contained tickets, each grounded in
exact current code and a concrete implementation approach, so they can be
handed to independent subagents with no prior context.
