docs(handoff): refresh post-v0.21.5 — anchor to new tag, reset menu state

Fold the six post-v0.21.4 commit narratives into CHANGELOG §
[0.21.5] (now the source of truth for that release's scope).
Reset the Since-cut log to "no threads in flight." Update
status (HEAD `a2432df`, tags through v0.21.5, tests still
1250/1249 passing pending the time-dependent flake clearing).
Resume prompt now anchors at v0.21.5 with the smaller post-cut
menu of next-finite-steps.

-  visual anchor points without needing to mentally bisect the
-  bar. Pure helper `scrub_notch_positions()` returns the fixed
-  array; spawn loop lives next to the WIN MOVE marker spawn so
-  the lifecycles match. Notches paint in `BORDER_SUBTLE`
-  (matches unfilled-track colour) and rely on extending past the
-  1px track (5px tall, anchored 2px above track top) for
-  visibility — same trick the WIN MOVE marker uses. Spawned
-  *after* the WIN MOVE marker so a notch and the marker landing
-  on the same percentage paint the marker on top. Mirrors the
-  notch ladder in `docs/ui-mockups/replay-overlay-mobile.html`.
-  4 new tests; 1228 → 1232.
-- **`d322abf` — `feat(replay): add percentage labels under
-  scrub-bar notches`.** First **layout-changing** commit in B-2's
-  screen-takeover arc. Banner height grew from 60 → 76 px to make
-  room for a 16 px label row beneath the 1 px scrub track; the
-  top row's `flex_grow: 1.0` still consumes the same 59 px so no
-  ripples on existing content. Pure helper `scrub_notch_labels()`
-  returns the fixed `["0%", "25%", "50%", "75%", "100%"]` array,
-  paired index-for-index with `scrub_notch_positions()`. Spawn
-  loop applies an "endpoints flush, middle three percent-anchored"
-  positioning pattern (Bevy 0.18 UI has no clean
-  `translate-x: -50%` primitive, so endpoints flush against
-  banner edges and middle three accept slight right-of-notch
-  offset). Label colour is `TEXT_SECONDARY` (mockup's
-  `BORDER_SUBTLE` reads as too low-contrast at 12 px against
-  `BG_ELEVATED_HI`). 4 new tests; 1232 → 1236.
-- **`1873b3f` — `feat(replay): add keybind-hint footer to
-  overlay banner`.** Second layout-changing commit in B-2's arc.
-  Banner grew from 76 → 92 px to fit a 16 px footer row at the
-  bottom edge with a vim-style mode line on the left
-  (`▌ NORMAL │ replay`) and a keybind-hint on the right
-  (`[SPACE] pause/resume`). Surfaces the existing Space
-  accelerator visually so CLAUDE.md §3.3's UI-first contract
-  holds for keyboard accelerators too. Footer lists *only
-  wired* keybinds — future commits that wire ESC for stop or
-  ← / → for prev/next will extend the right-hand text in
-  lockstep. Two pure helpers (`keybind_footer_mode_text`,
-  `keybind_footer_hint_text`) keep the static text testable;
-  shared `font_handle_for_labels` clone covers both label and
-  footer text spawns. 1px top border in `BORDER_SUBTLE`
-  separates the footer from the labels row. 4 new tests;
-  1236 → 1240.
-- **`90e24d9` — `feat(replay): wire ESC accelerator for stop,
-  gate pause modal`.** ESC during an active replay now stops it
-  (mirrors the Stop button click). New `handle_stop_keyboard`
-  system in `replay_overlay.rs` parallels `handle_pause_keyboard`
-  in shape. Cross-plugin coordination via `pause_plugin::toggle_pause`:
-  added a fourth defer-if check
-  (`replay_state.is_some_and(|s| s.is_playing())`) right after
-  `other_modal_scrims` and before `selection`. Symmetric to the
-  existing modal-stack defer pattern. Footer hint extended from
-  `[SPACE] pause/resume` → `[SPACE] pause/resume · [ESC] stop`
-  in lockstep with the wiring; the only-wired-keybinds
-  discipline holds. 3 new tests + 1 updated helper-pin test;
-  1240 → 1243.
-- **`23902cd` — `feat(replay): HC-mode coverage for
-  keybind-footer top border`.** Tag the footer's border-carrying
-  Node with `HighContrastBorder::with_default(BORDER_SUBTLE)` so
-  the existing `apply_high_contrast_borders` system bumps the
-  1 px top border from `#505050` → `#a0a0a0` under HC mode.
-  Footer text colours don't need bumps —
-  `TEXT_SECONDARY` (`#a0a0a0`) is already at `BORDER_SUBTLE_HC`
-  luminance by design (no `TEXT_SECONDARY_HC` constant exists).
-  The 1 px scrub track, notch ticks, and WIN MOVE marker render
-  via `BackgroundColor` (not `BorderColor`) so the marker
-  doesn't apply — HC coverage for those would need a
-  settings-aware paint system (precedent: `radial_rim_outline`
-  in `radial_menu`) and is deferred. 1 new test; 1243 → 1244.
-- **`e5c4f51` — `feat(replay): wire ← / → keyboard accelerators
-  for paused stepping`.** New `step_backwards_replay_playback`
-  in `replay_playback.rs` decrements the cursor and dispatches
-  `UndoRequestEvent`; the game's `handle_undo` reads it next
-  frame to reverse its most-recent move — hooking the existing
-  undo system rather than replaying forward from cursor 0
-  (every replay-applied move pushes to the undo stack the same
-  way a player move would, so undo is the right reversal
-  primitive). Both arrow keys are paused-only via the same
-  destructure-gate pattern the forward step uses. Footer hint
-  extended in lockstep:
-  `[SPACE] pause/resume · [ESC] stop · [← →] step`. Footer
-  reads "step" not the mockup's "scrub" — single-move step is
-  what's wired; continuous scrub would need a key-held event
-  source. `ReplayOverlayPlugin` gains
-  `add_message::<UndoRequestEvent>()` defensively. 6 new tests
-  (2 hint pins + 4 keyboard scenarios) + 1 updated helper-pin
-  test; 1244 → 1250 total tests, 1249 passing.
 
-**Pre-existing flake noted (verified):**
+Open next-step menu (B-2 keyboard accelerator coverage is now
-`daily_challenge_plugin::tests::
+complete; banner geometry is mutable):
-check_system_fires_warning_event_only_once_per_day` is
-time-dependent — fails when wall-clock UTC is within 30
-minutes of midnight (the daily-expiry warning window the test
-asserts against). Verified pre-existing by stashing all
-changes and re-running before commit — failure persisted. Same
-shape as the `winnable_seed_search` flake from earlier in the
-session. Will pass deterministically when UTC isn't in the
-warning window. Not introduced by recent work.
-
-Banner geometry is now mutable — every prior B-2 commit fit
-inside fixed 60 px space, but the notch-labels commit
-established the "grow the container, add a new flex-column
-child" precedent and the keybind-footer commit applied it
-again. The next sub-pieces need significantly more vertical
-room and follow the same shape.
-
-Next finite step on B-2: keyboard accelerator coverage is now
-complete (`Space` / `Esc` / `←` / `→`). Remaining choices:
 1. **HC-mode coverage for the scrub-track / notch ticks /
    WIN MOVE marker.** These render via `BackgroundColor` (not
    `BorderColor`) so `HighContrastBorder` doesn't apply.
    Pattern would mirror `radial_menu::radial_rim_outline` —
    per-frame paint reading `Settings::high_contrast_mode`.
-   Small commit, accessibility-progressing.
+   Smallest next commit.
 2. **Continuous scrub on key-held ← / →** instead of
    single-move step. Needs a key-held event source (or
    accumulator timer in the keyboard handler). Medium scope;
    matches the mockup's `[← →] scrub` terminology.
 3. **Move-log scroller / mini-tableau preview** — both need a
    much larger banner-height grow (effectively the takeover
-   container itself). Bigger arcs; the natural place to land
+   container itself). Multi-session arcs that close B-2.
-   the layout reflow that turns the banner into a takeover.
-4. **Cut a v0.21.5 patch release** rolling up the four
-   post-cut commits (`fe68861`, `d322abf`, `1873b3f`,
-   `90e24d9`, `23902cd`, `e5c4f51`) under the through-line
-   "replay-overlay scrubbing affordances + accessibility."
-   Coherent narrative; six commits is a normal-sized patch
-   bundle for this project.
 
-Recommended order: option 4 (cut release) is a clean next
+Recommended order: option 1 (HC paint for decorative pieces)
-boundary — six commits with a clear through-line is the right
+keeps the cadence small after a release cut. Option 3 is the
-size to bundle. Option 1 (HC paint for decorative pieces) is
