docs: CHANGELOG + SESSION_HANDOFF refresh for v0.13.0

CHANGELOG gains a [0.13.0] section covering the third UX iteration
round on top of v0.12.0:
- Tooltip-delay slider, streak fire, score-breakdown reveal
- Card backs follow active theme
- Drag-with-keyboard
- Right-click radial menu
Plus two code-review fixes (Removed: sccache wiring, Fixed: bundled-
only font handling).

The bottom-of-file compare links thread the new tag into the
existing chain. Test count updated to 1053.

SESSION_HANDOFF gains a "Session 7 round 3" table summarising the
six commits and rolls the punch list forward — UX candidate list
exhausted again, fresh six-item list seeded for a future round
(daily-challenge calendar, theme-picker thumbnails, per-mode high
scores, in-progress auto-save for Zen/Time Attack, configurable
scoring weights, win replays). Resume prompt asks A/B/C/D about
push, smoke-test, next round, or packaging.

+## [0.13.0] — 2026-05-02
+
+Third UX iteration round on top of v0.12.0. Six handoff candidates
+shipped — three small polish items, three larger interaction
+features (theme-aware backs, full keyboard play, right-click power
+shortcut). Plus two code-review fixes (font handling unified,
+sccache wiring removed).
+
+### Added
+
+- **Tooltip-delay slider** in Settings → Gameplay. `tooltip_delay_secs`
+  ranges [0.0, 1.5] in 0.1 s steps; "Instant" label when zero.
+  `Settings.tooltip_delay_secs` round-trips through serialise/deserialise
+  with `#[serde(default)]`. The hover-delay comparison in
+  `ui_tooltip` reads from `SettingsResource` with the existing
+  `MOTION_TOOLTIP_DELAY_SECS` as the test-fixture fallback.
+- **Win-streak fire animation.** New `WinStreakMilestoneEvent` fires
+  from `stats_plugin` when `win_streak_current` crosses any of
+  [3, 5, 10] (only the threshold crossing — not every subsequent
+  win). The HUD streak readout scale-pulses 1.0 → 1.20 → 1.0 over
+  `MOTION_STREAK_FLOURISH_SECS` (0.6 s).
+- **Score-breakdown reveal on the win modal.** Replaces the single
+  "Score: N" line with a per-component reveal (Base / Time bonus /
+  No-undo bonus / Mode multiplier / Total). Rows fade in over
+  `MOTION_SCORE_BREAKDOWN_FADE_SECS` (0.12 s) staggered by
+  `MOTION_SCORE_BREAKDOWN_STAGGER_SECS` (0.15 s). Honours
+  `AnimSpeed::Instant` by spawning all rows fully visible.
+- **Card backs follow the active theme.** `theme.ron`'s `back` slot
+  now actually drives the face-down sprite. Active-theme back
+  rasterises alongside the faces and supersedes the legacy
+  `back_N.png` picker. The picker remains as a fallback for themes
+  that don't ship a back, and the Settings UI surfaces a caption
+  ("Active theme provides its own back") + dimmed swatches when
+  the override is in effect.
+- **Keyboard-only drag-and-drop.** Tab cycles draggable card stacks,
+  Enter "lifts" the focused stack, arrow keys (or Tab) cycle the
+  legal-destination targets only, Enter confirms, Esc cancels. A
+  new `KeyboardDragState` resource models the two-mode flow without
+  changing the existing `SelectionState` contract. Mutual exclusion
+  with mouse drag uses a sentinel `DragState.active_touch_id =
+  KEYBOARD_DRAG_TOUCH_ID` (u64::MAX) so neither pipeline can
+  trample the other.
+- **Right-click radial menu.** Hold right-click on a face-up card →
+  a small ring of icons appears at the cursor with one entry per
+  legal destination. Release over an icon → fires
+  `MoveRequestEvent`; release in dead space, Esc, or left-click
+  cancels. Skips the drag motion entirely. New `RadialMenuPlugin`
+  owns the flow; co-exists with the existing `RightClickHighlight`
+  pile-marker tint.
+
+### Fixed
+
+- **Font handling consolidated to bundled-only.** Code-review
+  feedback: the SVG rasteriser previously mixed
+  `load_system_fonts` + bundled FiraMono + a lenient resolver,
+  which made card text rendering depend on host fontconfig. Picked
+  option (a) and applied it across both layers — `font_plugin` now
+  embeds `assets/fonts/main.ttf` via `include_bytes!()` and
+  registers it with `Assets<Font>`; `svg_loader::shared_fontdb`
+  loads only the bundled bytes; the new `bundled_font_resolver`
+  ignores the SVG's `font-family` request and always returns the
+  single bundled face. A parse failure aborts with a clear error
+  ("bundled FiraMono failed to parse — binary is corrupt").
+
+### Removed
+
+- **Project-level sccache wiring.** Code-review feedback: sccache
+  shouldn't be a per-project build dependency. Cargo's incremental
+  cache already covers the single-project case, and forcing
+  `rustc-wrapper = "sccache"` workspace-wide meant every contributor
+  had to install it. `.cargo/config.toml` deleted entirely; plain
+  `cargo build` now works without setup.
+
+### Documentation
+
+- `help_plugin` controls reference gains a "Mouse" section covering
+  double-click auto-move, right-click highlight, and the new
+  hold-RMB radial.
+- `help_plugin` also gains a "Keyboard drag" section for the new
+  Tab/Enter/Arrows/Esc flow.
+- Onboarding slide 3 picks up a `Tab → Enter` row referencing the
+  full keyboard drag path.
+
+### Stats
+
+- 1053 passing tests (was 1031 at v0.12.0 close).
+- Zero clippy warnings under `--workspace --all-targets -- -D warnings`.
+

 ## Where we are
 
-v0.11.0 shipped the headline structural changes (card themes, HUD overhaul, four UX feel wins, font fallback). The second UX round — six smaller items — is also done now. v0.12.0 is the right slice for them; together with the README refresh and CHANGELOG add it makes a clean release.
+Post-v0.12.0 the handoff listed six "next-round candidates" — every one shipped today plus two code-review fixes (font handling unified to bundled-only, sccache wiring removed). v0.13.0 is the right slice.
 
-The post-v0.11.0 UX candidate list is exhausted. Direction is open again.

 | Area | Commit | What landed |
 |---|---|---|
-| Font fallback | `fdb6c2e` | FiraMono bundled into the SVG fontdb so cards render rank/suit text on machines without Bitstream Vera Sans / Arial. Surfaced when a second-machine pull lost glyphs. |
-| Unlock foundations | `95df542` | `PileType::Foundation(Suit)` → `Foundation(u8)` with claim derived from the bottom card. Save schema 1 → 2; pre-v2 saves silently fall through to fresh game. |
-| Drop overlay | `f6c9166` | Soft fill + 3 px outline drawn ABOVE stacked cards for every legal target during drag. Replaces the hidden pile-marker tint. |
-| Drop shadows | `f712b89` | Each card casts a 25 % black shadow; lifts to 40 % with bigger offset/halo while in the active drag set. |
-| Stock badge | `655dfde` | "·N" chip at the top-right of the stock so players can see how close they are to a recycle. Hides at zero. |
-
-Tagged as `v0.11.0` (commit `063269c` plus URL refresh).

-## Session 7 round 2 (shipped 2026-05-02 afternoon) — v0.12.0
-
-| Area | Commit | What landed |
-|---|---|---|
-| Aspect ratio | `13aa0fd` | `CARD_ASPECT` 1.4 → 1.4523 to match hayeah SVG dimensions; cards no longer ~3.6 % squashed. Vertical-budget math adapts via the constant. |
-| Foundation flourish | `69ce9af` | King-on-foundation celebration: scale-pulse on the King, marker tints `STATE_SUCCESS`, synthesised C6→E6→G6 bell ping (~240 ms). New `FoundationCompletedEvent`. |
-| Drag-cancel tween | `525fe0f` | Illegal drops glide each card back to its origin over 150 ms with a quintic ease-out (Responsive curve, zero overshoot). Audio cue still fires. ShakeAnim retained for non-drag rejection paths. |
-| Focus pulse | `9887343` | Focus ring breathes at 1.4 s sin period over [0.65, 1.0] of native alpha. Static under `AnimSpeed::Instant`. |
-| Achievement onboarding | `ca5788f` | First-win toast "First win! Press A to see your achievements." plus persisted `shown_achievement_onboarding` flag so the cue fires exactly once. |
-| Mode Launcher shortcuts | `7dba772` | Digit 1–5 inside the Mode Launcher launches Classic / Daily / Zen / Challenge / TimeAttack. Locked modes silent no-op. Modal-scoped. |
-| Docs (rode along) | `d8c7034`, `9f095c4` | README refresh for v0.11.0 features and corrected controls table; CHANGELOG.md added covering v0.9.0–v0.11.0. |
-
-The first three items in this round (`13aa0fd`, `69ce9af`, `525fe0f`) shipped before the v0.11.0 tag's commit window closed; treating them as v0.12.0 since v0.11.0 was already cut at `063269c`.
+| Font fix | `17f9b51` | Code-review fix: bundle FiraMono via `include_bytes!()` in both `font_plugin` and `svg_loader`; drop `load_system_fonts`, drop the lenient resolver, drop the CSS-generic fallbacks. New `bundled_font_resolver` always returns the single bundled face. Parse failure aborts with a clear error. |
+| sccache removal | `13dd44b` | Code-review fix: deleted `.cargo/config.toml` and the `.cargo` directory. Plain `cargo build` works without per-project setup. |
+| Wave 1 bundle | `ddc8f27` | **Tooltip-delay slider** in Settings → Gameplay (0.0–1.5 s, 0.1 s steps, "Instant" label at zero). **Win-streak fire animation** at thresholds [3, 5, 10] via new `WinStreakMilestoneEvent`. **Score-breakdown reveal on win modal** with per-row stagger (Base / Time bonus / No-undo / Multiplier / Total), respects `AnimSpeed::Instant`. |
+| Card-back theming | `7ed4f2c` | The active theme's `back.svg` now actually drives the face-down sprite. Legacy `back_N.png` picker remains as a fallback for themes without a back; Settings caption surfaces when the override is in effect. |
+| Drag-with-keyboard | `a0fc0d2` | Tab → Enter → arrows → Enter completes a move without a mouse. New `KeyboardDragState` resource; mutual exclusion with mouse drag via `KEYBOARD_DRAG_TOUCH_ID` sentinel. Help + onboarding hotkey lists updated. |
+| Right-click radial | `b37f0cb` | Hold RMB on a face-up card → ring of icons at the cursor, one per legal destination; release over an icon → `MoveRequestEvent`. New `RadialMenuPlugin`. Help controls reference gains a "Mouse" section. |

+The v0.13.0 list is exhausted. Fresh candidates for a future round:
 
-- **Card-back theme support** — the current theme system swaps face SVGs but not the back. Players asked for animated backs in passing.
-- **Streak fire animation** in the HUD when win-streak crosses 3, 5, 10. Foundation flourish suggests the per-suit completion pattern; streak milestones are the lifetime equivalent.
-- **Score-breakdown reveal** at win — show base / time-bonus / no-undo bonus / mode multiplier as the score animates up. Currently the win modal just shows the final number.
-- **Right-click radial menu** for power users: hold right-click on a card → quick-drop options without dragging.
-- **Drag-with-keyboard** — Tab to a card, Enter to "lift", arrow keys to choose destination, Enter to drop. Keyboard-only completion of a game.
-- **Settings: tooltip-delay slider** so power users can disable the 0.5 s hover delay. Cheap.
+- **In-game daily-challenge calendar** — currently the daily challenge fires once on launch; a Settings or Profile-side calendar showing past days' completion / streak status would make the progression visible.
+- **Card-art preview in the theme picker** — Settings → Cosmetic shows theme name only; rendering the theme's Ace-of-Spades + back side-by-side as a thumbnail would make picking faster.
+- **Per-mode high-score readout** in the Stats screen. Currently lifetime stats roll all modes together.
+- **Auto-save in-progress games** in Zen / Time Attack so players who close the window mid-session don't lose their state.
+- **Configurable scoring weights** for the curious — Settings → Gameplay slider for time-bonus magnitude. Cosmetic but power-user appealing.
+- **Replay a winning game** — record the seed + move list at win time and offer "watch replay" from the Stats screen.

-- **Bundled default theme** ships in the binary via `embedded://` — 52 hayeah/playing-cards-assets SVGs (MIT) + a midnight-purple `back.svg` (original work).
