Two CSS issues in the kanban dashboard:
1. Columns overflow horizontally with no way to reach them — the
original scrollbar-width: none hid the scrollbar entirely, and
even with a scrollbar, a wrapping layout is better UX for a board
with 8+ columns. Changed to flex-wrap: wrap and removed the
overflow-x: auto + hidden scrollbar rules. Columns now flow into
multiple rows (~3 per row on a typical viewport) instead of
running off-screen.
2. .hermes-kanban-column-body lacked flex: 1 and min-height: 0,
so the flex child's implicit min-height: auto prevented it from
shrinking below its content size. Columns with many cards pushed
past the parent max-height instead of scrolling internally.
Verified: 9 columns wrap into 3 rows, all visible without
horizontal scroll. Done column (53 tasks) scrolls vertically
within its column bounds.
