docs(architecture): update to v1.3 — all Phase 8 gaps closed

Adds solitaire_wasm crate (§2/§3), replay API endpoints (§9), web
replay player routes, SyncProvider 7 optional methods, ThemePlugin +
SyncSetupPlugin in plugin table (§5), Settings new fields (§8), and
DB migration 002 replays table (§7). Also fixes missing [0.23.0]
section header in CHANGELOG.md.

+WebAssembly bindings for browser-side replay playback. Compiled to `cdylib` via `wasm-pack build`; the output lives in `solitaire_server/web/pkg/` and is served statically by the server.
+
+Intentionally **does not** depend on `solitaire_data` (which pulls in `dirs`, `keyring`, `reqwest`, and other non-WASM crates). Instead it defines a minimal `Replay` mirror with the same serde shape as `solitaire_data::Replay` — the JSON wire format is the compatibility contract.

+- `ReplayMove` / `Replay` mirrors — same serde shape as `solitaire_data` v2 equivalents

+Because `ReplayPlayer` uses the same `solitaire_core::GameState` as the desktop client, the two implementations cannot drift: the same seed + move list produces identical pile state at every step on both platforms.

+  no AVD round-trip test has been run. Required before Phase 8 sync goes live on

+- **Theme importer UI.** `import_theme()` (Phase 7, `theme/importer.rs`) is
+  complete but has no Settings button trigger. Players must copy theme files
+  manually.
+- **`mirror_achievement` decision.** `SyncProvider` has this method with a
+  no-op default; `SolitaireServerClient` never overrides it, no server endpoint
+  exists. Either implement (`POST /api/achievements/mirror` + client call on
+  `AchievementUnlockedEvent`) or delete from the trait.
+- **WASM build script.** `web/pkg/` contains compiled WASM committed to git.
+  Need a `build_wasm.sh` or Makefile target documenting the `wasm-pack build`
+  invocation to regenerate it.
+- **Server password reset.** No admin endpoint or CLI tool for resetting a
+  user's password. Self-hosters have no recovery path short of direct SQLite
+  edits.
 
-The visual-identity arc is effectively complete: token system,
+### 6. Testing gaps
-chrome migration, splash boot screen, replay-overlay banner,
+- **Server 401 → refresh → retry path** — the `pull`/`push` retry logic in
-card-face artwork (both rendering paths), and the `ACCENT_PRIMARY`
+  `SolitaireServerClient` has no integration test.
-palette refresh all shipped in v0.20.0 + v0.21.0. What stays open:
+- **WASM winning-replay step-through** — current tests cover 2 stock clicks;
+  a test stepping through a full winning sequence would catch
+  `GameState`/`ReplayMove` compatibility regressions.
 
-- *Replay-overlay screen-takeover redesign — closed 2026-05-08
+---
-  across 13 commits (v0.21.4–v0.21.7).* The full mockup
-  (`docs/ui-mockups/replay-overlay-mobile.html`) has shipped:
-  banner chrome (v0.21.0), floating MOVE chip (v0.21.2), WIN
-  MOVE scrub-bar marker (post-v0.21.3), playback controls /
-  Space accelerator (post-v0.21.3), scrub notches + labels +
-  keybind footer + ESC / ← / → accelerators + HC border
-  (v0.21.5), Move Log panel + HC scrub track + continuous
-  scrub (v0.21.6), and full-screen 50 % opacity dim layer
-  (v0.21.7). Every major B-2 sub-piece is now closed. The
-  only remaining items are minor polish: notch-label centering
-  and WIN MOVE HC contrast bump (see Open next-step menu).*
-- *Floating `MOVE N/M` chip above the focused card during
-  playback — closed 2026-05-08 by `2fb2d63`.* World-space
-  `Text2d` entity sibling to the banner overlay; uses the same
-  `LayoutResource` pile coordinates so it survives window
-  resizes without UI/camera math.
-- *Toast Warning variant wiring — closed 2026-05-08 by `279e23d`.*
-  Daily-challenge-expiry toast fires once per `daily.date` when
-  within 30 min of UTC midnight reset and today is incomplete.
-  `ToastVariant` is now fully load-bearing (every variant has at
-  least one real driver). Future Warning drivers can either reuse
-  the generic `WarningToastEvent(String)` carrier or add their
-  own domain message + `animation_plugin` handler.
-- *Toast Error variant wiring — closed 2026-05-08 by `68d50b5`.*
-  `MoveRejectedEvent` now fires a 2-second pink-bordered
-  "Invalid move" toast as the third leg of the
-  audio + visual + text rejection-feedback stool.
-- *High-contrast accessibility mode — closed 2026-05-08 by
-  `c5787c6` + `07e0357` (engine + UI) + v0.21.2's HC chrome
-  rollout (`c9af1ea` + `d87761d` + `ec804d5`) + post-cut
-  dynamic-paint rollout (`c153363`).* Card text rendering plus
-  8 static-border chrome surfaces (modal scaffold, tooltip,
-  onboarding key chips, help panel key chips, stats panel
-  cells, home Level/XP/Score row, home mode buttons, home
-  mode-hotkey chips, 4 settings panel surfaces) all boost
-  borders to `BORDER_SUBTLE_HC` under HC via the
-  `HighContrastBorder` marker. The previously-carved-out
-  dynamic-paint sites are now also covered: HUD action buttons
-  and modal buttons take the same marker (their paint cycles
-  only mutate `BackgroundColor`, so no race); the radial menu
-  rim folds HC into its per-frame spawn via
-  `radial_rim_outline` so the focused rim boosts to
-  `BORDER_SUBTLE_HC` under HC (preserving focused-vs-resting
-  hierarchy that naive marker substitution would invert).
-- *Reduced-motion mode — closed 2026-05-08 by `c5787c6` +
-  v0.21.2's `ed152e2`.* `effective_slide_secs` forces 0 on
-  card animations; `pulse_splash_cursor` skips the per-frame
-  pulse multiplier; `spawn_splash` skips the scanline overlay
-  entirely. Future scope: gate any future card-lift z-bump
-  animation, warning-chip pulse (when one materialises).
 
-### Carried forward from v0.19.0
+## ARCHITECTURE.md gaps (for the update pass)
 
-- *App icon round — closed 2026-05-08 by `3eb3a26` + `716a025`.*
+Items missing from the doc:
-  Runtime `Window::icon` wired (Linux/macOS/Windows); 9-size
+1. `solitaire_wasm` crate (§2 workspace + §3 responsibilities)
-  PNG hierarchy at `assets/icon/icon_<size>.png` covers Linux
+2. Replay API endpoints (§9 API Reference — 3 new routes)
-  hicolor + downstream `.icns`/`.ico` packaging needs. The
+3. Web replay player route (`/replays/:id` + `ServeDir /web`)
-  `.ico` and `.icns` bundle-format files themselves are *not*
+4. `SyncProvider` trait: 6 added methods
-  generated — both would need new crate deps (`ico` and
+5. Theme system in Bevy plugin table (§5)

-### Other small candidates
+---
 
-- *Play-by-Seed dialog — closed 2026-05-08 by `0cb1587`.*
+## Process notes
-  `PlayBySeedPlugin` adds a numeric-input modal with async solver
-  preview (debounced 500 ms). `HomeMode::PlayBySeed` card fires
-  `StartPlayBySeedRequestEvent`. 5 unit tests. 75 new verified-win
-  seeds (`2062bd0`) expand `CHALLENGE_SEEDS` via the new
-  `solitaire_assetgen::gen_seeds` binary.
-- *Prev/Next selector chips spawn site — closed 2026-05-08 by
-  `a449f60`.* `ReplayPrevButton` / `ReplayNextButton` /
-  `ReplaySelectorCaption` / `ReplaySelectorDetail` now spawn in
-  `spawn_stats_screen` as a compact chip row above the Watch
-  Replay action. The Shareable badge is in the detail line.
-  The click handler and repaint systems were already live since
-  v0.19.0; this was purely the missing spawn site.
-- **Toast queue / immediate unification.** The two toast paths
-  (`spawn_queued_toast` for `InfoToastEvent` queue; `spawn_toast`
-  for fire-and-forget) now share visual treatment but remain
-  separate functions because they serve different temporal
-  needs (sequential vs. parallel). If overlap becomes a UX
-  issue, merge into one queue with priority lanes.

+- **Commit attribution:** use `funman300` as git user. Co-author line:
+  `Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>`.
+- **Commit format:** `type(scope): description` per CLAUDE.md §7.
+- **Never commit without:** `cargo test --workspace` passing + clippy clean.
+- **Sub-agents** stage/verify only; orchestrator commits.
+- **`CARD_PLAN.md`** referenced in `theme/` module comments but not present in
+  repo. Clean up references or commit the file.
+- **Token-port pattern** (v0.20.0): when migrating tokens, walk every concrete
+  artifact downstream — PNGs, SVGs, literals, comments. Three "walked past this"
+  follow-ups in v0.21.0 all had this shape.
 
-- **The desktop-adaptation spec is the canonical reference for
+---
-  geometry decisions** when porting any future plugin. Read
-  `docs/ui-mockups/desktop-adaptation.md` first; apply the
-  universal rules to every surface; consult the per-screen
-  table for the priority surfaces. The 9 missing-plugin screens
-  (splash now ported; eight remaining) inherit the universal
-  rules without dedicated guidance.
-- **Stitch `generate_variants` is unreliable for layout-only
-  adaptation prompts** as of 2026-05-07. The first call timed
-  out and no variant ever landed in `list_screens`. If a future
-  session wants visual desktop mockups, prefer
-  `generate_screen_from_text` with a fresh narrow prompt per
-  screen rather than `generate_variants` against existing
-  mobile screens.
-- **Token-port pattern.** v0.20.0's chrome-migration commits
-  set a reusable shape for "centralised design system applied
-  across N plugins":
-  1. Constants module (`ui_theme.rs`) is the source of truth.
-  2. Const sites that can't call `Alpha::with_alpha` (not yet
-     `const` on stable) use a literal RGB matching the token,
-     with a unit test pinning the RGB to the token (e.g.
-     `MARKER_VALID`, `HINT_PILE_HIGHLIGHT_COLOUR`,
-     `RIGHT_CLICK_HIGHLIGHT_COLOUR`).
-  3. Cross-plugin duplication (e.g. `MARKER_DEFAULT` ↔
-     `PILE_MARKER_DEFAULT_COLOUR`) collapses to a single
-     promoted const re-exported from one plugin and imported
-     by the other — replaces "kept in sync" doc comments with a
-     compile-time invariant.
-  4. Domain colours (suit pips, card faces, lerp helpers) stay
-     as literals with a comment naming the rationale; only UI
-     chrome routes through tokens.
-- **`SplashFadable` scaffolding pattern** (introduced in
-  `cacb19c`). Any future overlay that needs to fade `N >> 3`
-  elements together should follow the same shape: one tiny
-  marker carrying the full-alpha base colour, one global query
-  that lerps every marker's alpha each frame, no per-element
-  query plumbing. Cleanly outscales the `Without<X>, Without<Y>`
-  query exclusion pattern that the old splash was hitting at
-  three siblings.

-### Canonical remote
-
-`github.com/funman300/Rusty_Solitaire` is the canonical repo.
-Always push there. As of v0.21.0 origin matches local; the next
-push happens when post-cut work accumulates and is ready to roll
-into a v0.21.1 / v0.22.0 cut.
-
-### Design direction (Terminal — base16-eighties)
-
-- **Tone:** retro-terminal / synthwave — flat depth (no box-shadows),
-  monospaced-forward typography (JetBrains Mono / FiraMono), tight
-  16 px edge margins, 8 px card radius.
-- **Palette:** near-black surface ramp (`#151515` / `#202020` /
-  `#2a2a2a` / `#353535`), brick-red primary CTA (`#a54242` —
-  swapped from cyan `#6fc2ef` in v0.21.0 commit `a292a7e`), lime
-  success (`#acc267`), gold warning (`#ddb26f`), pink error /
-  suit-red (`#fb9fb1`), lavender celebration (`#e1a3ee`), teal
-  info (`#12cfc0`).
-- **Two-color suits.** Red = `#fb9fb1`, black = `#d0d0d0`.
-  Outlined glyphs for diamonds & clubs are *always on*; the
-  Settings "color-blind mode" toggle swaps red → lime `#acc267`
-  (was red → cyan pre-v0.21.0; lime is the next-best non-red
-  base16-eighties accent now that the primary itself is red).
-- **Card glyphs render upright in both corners** — no 180°
-  inverted-corner-indicator rotation. Single-orientation
-  digital play doesn't benefit from the traditional flip-
-  readback convention. `design-system.md` § Game Cards
-  documents this deliberate deviation.

-DECISION TO ASK THE PLAYER FIRST:
+OPEN WORK (in priority order):
-  A. Android follow-ups — JNI ClipboardManager bridge (arboard
+  B. Leaderboard best-score auto-post (server sync handler + optional
-     has no Android backend), Android Keystore (blocked on Phase 8).
+     GameWonEvent path in sync_plugin)
-     Launch verification + double-tap are closed.
+  C. Refresh token rotation (server auth handler + new column/table)
-  B. Phase 8 (sync) — local storage scaffolding, self-hosted
+  D. Android AVD functional tests (Keystore + clipboard)
-     Axum server, `SolitaireServerClient` impl. The biggest open
+  E. Theme importer UI button in Settings
-     arc by scope; rolls up Android dependencies (Keystore,
+  F. mirror_achievement: decide + implement or remove from trait
-     ClipboardManager).
-  C. Play-by-Seed polish — the dialog is functional but has no
-     visual preview of the solver verdict in the UI yet; the
-     HomeMode card is wired but the dialog spawn site and verdict
-     display could use a second pass.
 
-WORKFLOW NOTES:
+Ask which to start. All are independent; any is a valid next arc.
-  - Use the system git config (already correct).
-  - When attributing playtester feedback in commits/docs, use
-    "Quat" not "Rhys" (saved feedback memory).
-  - Sub-agents stage + verify only; orchestrator commits.
-  - Every commit must pass build / clippy / test before pushing.
-  - Push to GitHub (origin) — gh auth setup-git wired on
-    primary dev box; verify on laptop before first push.
-  - Token-port pattern: when migrating tokens, walk every
-    concrete artifact downstream of the token (PNG textures,
-    embedded SVGs, hardcoded literals, comment color names),
-    not just the token name. v0.21.0 surfaced three "the
-    migration walked past this" follow-ups that all matched
-    this shape — codified here so future similar work can
-    pattern-match instead of rediscovering.
-  - Doc-vs-implementation drift pattern: v0.21.1's pile-marker
-    visibility fix (`4d48cad`) implemented an invariant that
-    had been declared in a module doc comment but was never
-    enforced in code. When future work touches a module with
-    a "this does X" doc comment, verify the code actually does
-    X and add a test if not. Two layers, two checks.
-
-OPEN AT THE START: ask which of A–C. Don't pick unilaterally.
-Note: every remaining option is multi-session by nature (A is
-gated on Android tooling; B and C are explicitly multi-session
-arcs). A fresh session is a better fit for any of them than the
-tail of a long working stretch.
