funman300 c5787c6953 feat(accessibility): wire high-contrast + reduce-motion modes through engine
Resume-prompt Option F, part 1 of 2. Adds two accessibility flags
to Settings and threads each through the engine surfaces that
react to them. Settings UI toggle rows follow in a separate
commit; players who want to test today can edit `settings.json`
manually.

Spec at `docs/ui-mockups/design-system.md` §Accessibility (#2 and
#3).

### High-contrast mode

`Settings::high_contrast_mode: bool` (defaults to false; serde-
default for back-compat). When on:

- Red-suit text colour boosts from `RED_SUIT_COLOUR` (`#fb9fb1`)
  to a new `RED_SUIT_COLOUR_HC` (`#ff8aa0`).
- Black-suit text colour boosts from `BLACK_SUIT_COLOUR`
  (`#d0d0d0`) to a new `TEXT_PRIMARY_HC` (`#f5f5f5`).
- New `BORDER_SUBTLE_HC` (`#a0a0a0`) constant available for
  future chrome-side wiring (this commit only routes HC through
  card text rendering — chrome border boost is a separable
  follow-up).

The HC and CBM flags compose. CBM red→lime wins over HC on red
suits when both are on (lime is itself a high-luminance accent,
so the HC boost has nothing further to do). HC still applies to
black suits when both flags are on (CBM doesn't touch black).
Four new `text_colour` tests pin the truth table.

### Reduce-motion mode

`Settings::reduce_motion_mode: bool` (defaults to false; serde-
default for back-compat). When on:

- Card-slide animation duration is forced to `0.0` regardless of
  the player's `AnimSpeed` selection — cards snap instantly to
  their target position. Implemented by extracting a new
  `effective_slide_secs(&Settings)` helper that wraps
  `anim_speed_to_secs` with the reduce-motion gate.
- Future scaffolding hooks (splash scanline, warning-chip pulse,
  card-lift z-bump animation) follow the same `if
  settings.reduce_motion_mode { skip }` pattern when wired —
  stays out of scope for this commit since each motion path
  needs its own per-system gate.

Two new tests cover the gate behaviour and the fall-through-to-
AnimSpeed pass-through path.

### Threading

`text_colour` signature extended with a `high_contrast: bool`
parameter; `sync_cards` / `sync_cards_startup` /
`sync_cards_on_change` / `sync_cards` core / `spawn_card_entity`
/ `update_card_entity` all gain a parallel parameter mirroring
the existing `color_blind: bool` plumbing. Verbose but matches
the established pattern; a future refactor could pack both into
an `AccessibilityView` struct, but bigger blast radius.

### Stats

1191 passing / 0 failing across the workspace (net +6 from
v0.21.0's 1185 baseline once the icon-pin test landed):
- 4 new `text_colour` HC tests in `card_plugin`
  (red-suit boost, black-suit boost, CBM-wins-on-red,
  black-suits-with-CBM+HC-still-boost).
- 2 new `effective_slide_secs` tests in `animation_plugin`
  (zero-out under reduce-motion, fall-through to AnimSpeed when
  off).

`cargo clippy --workspace --all-targets -- -D warnings` clean.

Solitaire Quest

A cross-platform Klondike Solitaire game written in Rust, with a card-theme system, full progression (XP / levels / achievements / daily challenges), and optional self-hosted sync so your stats follow you across machines.

Features

  • Klondike Solitaire — Draw One and Draw Three modes; foundations are unlocked (any Ace lands in any empty slot, the slot then claims that suit)
  • Card themes — bundled hayeah/playing-cards-assets default plus user-installable themes (drop a directory under the data dir or import a zip from Settings → Cosmetic)
  • Modern HUD — reserved top band keeps cards from crowding the score readout; the action bar auto-fades when the cursor leaves it so it can't compete with the play surface
  • Drag feel — every legal drop target is highlighted in green during drag; cards cast a soft drop shadow that lifts when picked up; the stock pile shows a remaining-count chip so you can see how close you are to a recycle
  • Keyboard navigation — Tab cycles focus through buttons, arrow keys move within picker rows, Enter activates; works across every modal and the HUD action bar
  • Progression — XP, levels, unlockable card backs and backgrounds
  • 19 Achievements — including secret ones
  • Daily Challenge — server-seeded so every player worldwide gets the same deal
  • Leaderboard — opt-in, powered by your own self-hosted server
  • Special Modes (unlocked at level 5): Zen, Time Attack, Challenge
  • Sync — pull/push stats across devices via a self-hosted server
  • Color-blind mode — blue tint on red-suit cards alongside the suit glyph

Building

Prerequisites

  • Rust stable toolchain (rustup install stable)
  • Linux: libasound2-dev libudev-dev libxkbcommon-dev
  • macOS: Xcode Command Line Tools
# Fast development build
cargo run -p solitaire_app --features bevy/dynamic_linking

# Release build
cargo build -p solitaire_app --release
./target/release/solitaire_app

Controls

Every action also has a visible UI button — keyboard shortcuts are optional accelerators.

Key Action
Left click / drag Move cards
Double click Auto-move card to its best legal destination
Right click Highlight legal moves for a card
Space / D Draw from stock
U Undo
H Hint (highlight a legal move)
N New game
Z Zen mode
G Forfeit (during pause)
Tab / Shift+Tab Cycle keyboard focus
Enter Activate focused button / auto-complete (when badge is lit)
Esc Pause / dismiss modal
F1 Help / controls
F11 Toggle fullscreen
S / A / P / O / L / M Stats / Achievements / Profile / Settings / Leaderboard / Menu

Card themes

The default theme ships embedded in the binary, so the game runs self-contained with no external assets. To install another theme, drop a directory containing a theme.ron manifest plus 53 SVG files (52 faces + 1 back) under the platform data dir's themes/ folder, or import a zip from Settings → Cosmetic. The picker chip lights up the moment a new theme is registered. Themes are SVG-based, so they rasterise cleanly at whatever resolution the window happens to be.

Sync Server (optional)

To sync stats across machines, run the self-hosted server. See README_SERVER.md for setup instructions.

Once the server is running, open Settings → Sync Backend, enter the server URL and your username, and register an account from within the game.

Running Tests

# All tests (982 passing as of v0.11.0)
cargo test --workspace

# Just game logic (no display required)
cargo test -p solitaire_core -p solitaire_sync -p solitaire_data -p solitaire_server

# Lint
cargo clippy --workspace --all-targets -- -D warnings

Credits

Built on Bevy and the wider Rust ecosystem (Tokio, Axum, sqlx, Serde, kira, and many more). Card faces come from hayeah/playing-cards-assets (MIT, derived from the public-domain vector-playing-cards library); the default card back is original work; the UI font is FiraMono-Medium (OFL). All audio is synthesized programmatically by this project. See CREDITS.md for the full list and license details.
