Boards, lanes, and cards all show their frontmatter icon leading the
row, tinted through the palette with a secondary fallback; the board
scanner now reads icon and iconColor from the same one-file parse as
the title. Lane and card lists gain the segmented Manual/Name/Recent
control — display-only sorting layered over the rank order, never
rewriting what's on disk.
