The activity window shrinks from a week to two hours in 24 five-minute
buckets (12 braille cells), bucketed newest-first so "now" sits at the
left edge and traffic slides right as it ages. Bar heights switch from
peak-relative scaling to absolute tiers (1/3/8/21 messages per dot), so
the same traffic draws the same bar on every row, and silent cells drop
to a faint two-bottom-dot baseline — a quiet channel reads as a flatline
rather than a gap. The Reorder row's narrow ↕ arrow gains a second space
so its label aligns with the two-cell glyphs of its sibling rows.
