The fixed 120px/96px caps on the two wrapped layouts were row counts in disguise: a
third row was clipped into a ~4px scroller, hiding tabs inside a container nothing
invites you to scroll, while the header had the page below it to grow into. Both
layouts now share one rule capped at var(--tab-strip-max-height, 40vh), a safety net
for an absurd session count rather than a row limit.
Verified before shipping: .header is min-height + flex-shrink: 0 so it can grow, and
terminal-ui's ResizeObserver refits the terminal when it does; updateTabOverflowMode()
returns early for any non-desktop viewport, and below 1024px mobile.css pins the header
to max-height: 48px, so this is desktop-only in effect; the selector is comma-grouped
rather than :is(), so each arm keeps (0,2,0) and mobile.css's overrides still win on
source order. PostCSS parses the file cleanly (prettier ignores styles.css).
