docs: cut v0.21.5 — replay-overlay scrubbing affordances + accessibility

Patch release rolling up six post-v0.21.4 commits under the
through-line "replay-overlay scrubbing affordances + accessibility":

- fe68861: quarter-mark scrub-bar notches
- d322abf: percentage labels under notches (banner 60 → 76 px)
- 1873b3f: keybind-hint footer (banner 76 → 92 px)
- 90e24d9: ESC accelerator + cross-plugin pause-modal gate
- 23902cd: HC-mode coverage for footer top border
- e5c4f51: ← / → keyboard accelerators for paused stepping

v0.21.4 shipped pause / resume / step + the WIN MOVE marker as
the first scrubbing-shaped additions; v0.21.5 fills out the rest
of the scrubbing UX so the player has both visual anchor points
(notches + labels) and a complete keyboard control surface
(Space / Esc / ← / →) for navigating a paused replay.

Two of the six commits are layout-changing — they grow the
banner from 60 → 76 → 92 px to make room for the notch labels
and keybind footer. Banner geometry was fixed for every prior
B-2 commit; this release establishes the "grow the container,
add a flex-column child" pattern that the remaining B-2
sub-pieces (move-log scroller, mini-tableau preview) will
inherit when they land.

Tests: 1228 → 1250 (+22 net new), 1249 passing, 1 pre-existing
time-dependent flake (daily_challenge warning, fails when UTC
clock is within 30 min of midnight; verified not introduced by
this release).

Clippy clean.

## [0.21.5] — 2026-05-08
Patch release for the post-v0.21.4 work. One through-line:
**replay-overlay scrubbing affordances + accessibility**. v0.21.4
shipped pause / resume / step + the WIN MOVE marker as the first
*scrubbing-shaped* additions to the replay overlay; v0.21.5
fills out the rest of the scrubbing UX so the player has both
visual anchor points (notches + labels) and a complete keyboard
control surface (Space / Esc / ← / →) for navigating a paused
replay.
Two of the six commits in this cycle are layout-changing — they
grow the banner height from 60 px → 76 px → 92 px to make room
for the notch labels and keybind footer. Banner geometry was
fixed for every prior B-2 commit; this release establishes the
"grow the container, add a flex-column child" pattern that the
remaining B-2 sub-pieces (move-log scroller, mini-tableau
preview) will inherit when they land.
### Added
- **Quarter-mark scrub-bar notches** (`fe68861`). Five 1 px
vertical ticks at 0 / 25 / 50 / 75 / 100 % give the player
visual anchor points without needing to mentally bisect the
bar. Pure helper `scrub_notch_positions()` returns the fixed
array; spawn loop sits next to the WIN MOVE marker spawn so
the lifecycles match. Notches paint in `BORDER_SUBTLE` (same
as the unfilled track) and rely on extending past the 1 px
track (5 px tall, anchored 2 px above the 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.
- **Percentage labels under each notch** (`d322abf`). Five
`0%` / `25%` / `50%` / `75%` / `100%` labels in a new 16 px
row beneath the 1 px scrub track give the player explicit
quarter-mark readouts. Banner grew from 60 → 76 px to
accommodate the row — first **layout-changing** commit in
the B-2 arc. Pure helper `scrub_notch_labels()` returns the
fixed array, paired index-for-index with
`scrub_notch_positions()`. Spawn loop applies an "endpoints
flush, middle three percent-anchored" positioning pattern:
leftmost label gets `left: 0`, rightmost gets `right: 0`,
middle three anchor at `left: Val::Percent(p)` since Bevy
0.18 UI lacks a clean CSS-style `translate-x: -50%`
centering primitive. Label colour is `TEXT_SECONDARY`
rather than the mockup's `BORDER_SUBTLE` (the latter would
match the notches but is too low-contrast against
`BG_ELEVATED_HI` to read at 12 px).
- **Keybind-hint footer** (`1873b3f`). Vim-style mode line on
the left (`▌ NORMAL │ replay`) plus a keybind hint on the
right at the bottom edge of the banner. Banner grew from
76 → 92 px to fit the 16 px footer row. Surfaces every
wired keyboard accelerator visually so CLAUDE.md §3.3's
UI-first contract holds for keyboard accelerators too. The
footer lists *only* keybinds that are actually wired —
the only-wired-keybinds discipline means each release
cycle's hint string is a precise honest contract with the
player. Two pure helpers (`keybind_footer_mode_text`,
`keybind_footer_hint_text`) keep the static text testable.
1 px top border in `BORDER_SUBTLE` separates the footer
from the labels row.
- **ESC keyboard accelerator for replay-stop** (`90e24d9`).
New `handle_stop_keyboard` system parallels
`handle_pause_keyboard` in shape — fires only when state
is `Playing`, calls `stop_replay_playback`. 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 the existing `other_modal_scrims` check so ESC
during active replay belongs to the replay overlay, not
the pause modal.
- **HC-mode coverage for the keybind-footer top border**
(`23902cd`).
`HighContrastBorder::with_default(BORDER_SUBTLE)` marker
on the footer's border-carrying Node so the existing
`apply_high_contrast_borders` system bumps the 1 px top
border from `#505050``#a0a0a0` when
`Settings::high_contrast_mode` is on. Without the marker
the footer reads as floating loose under HC because the
border that anchors it to the labels row is
near-invisible.
- **← / → keyboard accelerators for paused stepping**
(`e5c4f51`). 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. Hooks the
existing undo system rather than replaying-forward-from-
zero — 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.
The mockup labels these `[← →] scrub`; single-move step
is the closest behaviour shippable today, so the footer
hint reads `[← →] step` — only-wired-keybinds discipline.
### Changed
- **Banner height grew 60 → 76 → 92 px** across two
layout-changing commits (`d322abf` then `1873b3f`). Top
row's `flex_grow: 1.0` still consumes 59 px so the
existing content (label / progress chip / buttons) has
the same vertical space; the new rows (16 px labels +
16 px footer) extend the banner downward into the
gameplay area. Banner geometry is now mutable — every
prior B-2 commit fit inside fixed 60 px space.
- **Keybind-footer hint text grew alongside the wirings**:
`[SPACE] pause/resume`
`[SPACE] pause/resume · [ESC] stop`
`[SPACE] pause/resume · [ESC] stop · [← →] step`.
- **`pause_plugin::toggle_pause` now defers when a replay
is active** (`90e24d9`). Adds a fourth defer-if check to
the existing modal-stack pattern.
- **`ReplayOverlayPlugin` registers
`add_message::<UndoRequestEvent>()`** (`e5c4f51`).
Defensive registration so the plugin runs cleanly under
`MinimalPlugins` without `GamePlugin` attached.
### Documentation
- `SESSION_HANDOFF.md` refreshed five times this cycle.
The B option in the Resume menu now traces the full arc:
notches → labels → footer → ESC → HC → arrow keys.
- The pre-existing `daily_challenge` warning test that
fails when wall-clock UTC is within 30 minutes of
midnight is documented in this cycle's handoff. Same
shape as the earlier `winnable_seed_search` flake —
time-dependent, deterministically passes outside the
trigger window.
### Stats
- **1250 total tests / 1249 passing / 1 pre-existing
time-dependent flake** across the workspace (net +22 from
v0.21.4's 1228 baseline):
- 4 from `fe68861` (scrub-notch coverage)
- 4 from `d322abf` (notch-label coverage)
- 4 from `1873b3f` (keybind-footer coverage)
- 3 from `90e24d9` (ESC-accelerator coverage)
- 1 from `23902cd` (HC-marker coverage)
- 6 from `e5c4f51` (arrow-keyboard coverage)
- **Pre-existing flake**:
`daily_challenge_plugin::tests::check_system_fires_warning_event_only_once_per_day`
fails when wall-clock UTC is within 30 minutes of
midnight. Verified pre-existing by stash-and-retest
before each commit. Will pass deterministically outside
the trigger window. Not introduced by this release.
- Clippy clean across the workspace.
