pub fn render_tab_empty(frame: &mut Frame<'_>, area: Rect, e: &TabEmpty<'_>)Expand description
Render an inner empty-state card centred horizontally inside area.
Caller is responsible for the outer block (e.g. the existing
main_block_line with the row-count title) — that outer frame is
preserved so the empty state reads as a state OF the tab, not as a
replacement screen.
Width: clamped to [40, 78] columns so the card never hugs the
outer border on a 200-col terminal and never overflows on a narrow
one. When area.width is below 44 the card collapses to a single
2-space-indented line via render_empty_with_hint using the first
hint as the affordance — graceful degradation without a new code
path on the caller side.
