Vim-style mode line on the left (`▌ NORMAL │ replay`) plus a
keybind-hint on the right (`[SPACE] pause/resume`) gives the
existing Space accelerator a visible UI counterpart, satisfying
the UI-first contract from CLAUDE.md §3.3 for the keyboard
accelerator that v0.21.4 shipped.
The footer lists only keybinds that are *actually wired today*.
Future commits that wire ESC for stop or ← / → for prev/next
move will extend the right-hand text in lockstep — the footer
never lists aspirational keybinds (would lie to users).
Banner height grew from 76 → 92 px to make room for the 16 px
footer row. Second layout-changing commit in B-2's screen-
takeover arc; same "grow container, add flex-column child"
pattern as the notch-labels commit. 1px top border in
BORDER_SUBTLE separates the footer from the notch-label row.
Two pure helpers (`keybind_footer_mode_text`,
`keybind_footer_hint_text`) keep the static text testable
without per-text marker components on the inner Text entities.
The shared `font_handle_for_labels` clone covers both label and
footer text spawns since the labels closure only `.clone()`s
the handle (never moves it).
4 new tests: pure-helper guards, footer-spawn cardinality
(exactly one), text-set assertion (both helper strings appear as
descendants), lifecycle parity with the overlay tree.
Tests: 1236 → 1240 (+4). Clippy clean.
