Project-wide palette shift at user request. Replaces the cyan primary accent everywhere it surfaces — splash boot screen, home menu glyphs, action chevrons, replay overlay banner + scrub fill + chip border, achievement checkmarks, leaderboard #1 indicator, radial menu fill, focus ring, card-back canonical badge, etc. — with `#a54242` from the same base16-eighties family as the existing pink suit colour. Knock-on changes that all land in this commit per the lockstep rule: - ui_theme.rs: ACCENT_PRIMARY (#a54242), ACCENT_PRIMARY_HOVER (#c25e5e brightened companion), FOCUS_RING (same hue, 0.85 alpha). Module-level palette comment + STOCK_BADGE_FG + CARD_SHADOW_ALPHA_DRAG doc strings updated to match. - card_plugin.rs: card_back_colour(0) now returns the brick-red ACCENT_PRIMARY (was cyan). RED_SUIT_COLOUR_CBM swapped from cyan to lime #acc267 — the CBM alternative needs to stay hue-distinct from the new red-family primary, lime is the next-best non-red base16-eighties accent. text_colour doc + CBM tests renamed cyan→lime in lockstep (text_colour_color_blind_mode_swaps_red_suits_to_lime). - card_face_svg.rs: BACK_ACCENTS[0] now "#a54242" (canonical Terminal back). - splash_plugin.rs / ui_modal.rs / replay_overlay.rs / selection_plugin.rs: descriptive "cyan" comments swapped to "accent" / "primary-accent" wording so the doc strings stay decoupled from any specific hue. Future palette tweaks won't require comment churn. - design-system.md: YAML token frontmatter updated (primary, surface-tint, suit-red-cb, primary-container, on-primary-container, inverse-primary). Palette table gains a project-specific `base08` slot for the new red. CTA / Selection / Card-back badge / Primary button / Bottom-bar active-icon / glow / CBM swap text all retuned. Historical references preserved (e.g. "Was cyan #6fc2ef before the 2026-05-08 swap") so the audit trail stays in the spec. - card_face_svg_pin.rs: rebaselined. Exactly one hash drift (back_0 — the canonical Terminal back's badge changed colour). Other 56 hashes identical (face SVGs don't reference the accent; back_1..4 use unchanged accents). The one-hash-drift signal confirms the change scope was surgical. Workspace clippy + cargo test --workspace clean, 1184 passing. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

## Brand & Style
|
||
|
||
The "Terminal" design system replaces the previous "Premium Solitaire" calm-indie aesthetic with a **retro-terminal / synthwave** identity. The intent is the visual confidence of a well-tuned terminal emulator (think Berkeley Mono dotfiles, base16-eighties, CRT phosphor): monospaced, dense, legible, snappy. It is *not* casino-glitz, *not* skeuomorphic felt, and *not* whimsical.
|
||
|
||
The personality is **technical, deliberate, slightly playful**. Cards are flat with thin colored strokes; the HUD reads like a status bar; modals look like terminal panes. Motion is short and snap-easing — no bouncy springs. Long-session calm is preserved by keeping the chroma low and reserving saturated accents for *meaning* (CTAs, feedback, celebrations) rather than decoration.
|
||
|
||
Influences: base16-eighties (Chris Kempson), Berkeley Mono, Vim/Neovim status lines, the iA Writer aesthetic, classic CRT phosphor with no chromatic aberration.
|
||
|
||
## Palette
|
||
|
||
The palette is base16-eighties — a 16-slot terminal palette where indices 00–07 form a monochrome ramp and 08–0F provide saturated accents. We map base16 slots to Material Design 3 token roles below.
|
||
|
||
### Source palette (base16-eighties)
|
||
|
||
| Slot | Hex | Role |
|
||
|---|---|---|
|
||
| base00 | `#151515` | background |
|
||
| base01 | `#202020` | surface-container |
|
||
| base02 | `#303030` | line-highlight (subtle) |
|
||
| base03 | `#505050` | outline / muted text |
|
||
| base04 | `#b0b0b0` | secondary text |
|
||
| base05 | `#d0d0d0` | foreground / on-surface |
|
||
| base06 | `#e0e0e0` | bright text |
|
||
| base07 | `#f5f5f5` | brightest highlight |
|
||
| base08 | `#fb9fb1` | red — used for `error`, `suit-red` |
|
||
| base09 | `#ddb26f` | orange — used for warning chips |
|
||
| base0A | `#acc267` | yellow/lime — used for `highlight-valid` (drag targets, valid moves) |
|
||
| base0B | `#12cfc0` | green/teal — used for `highlight-info` (toasts, neutral status) |
|
||
| base0C | `#6fc2ef` | cyan/sky — historically the primary CTA; now reserved for ad-hoc accents only |
|
||
| base0D | `#6fc2ef` | (alias) |
|
||
| base08 (project) | `#a54242` | brick red — primary CTA, focus ring, `selection` (project-specific extension; the base16-eighties `base08` slot is `#fb9fb1` pink which we keep as `error`/`suit-red`) |
|
||
| `suit-red-cb` slot | `#acc267` | lime — color-blind-mode swap for red suits (was `#6fc2ef` cyan before the 2026-05-08 primary-accent swap; lime is the next-best non-red base16-eighties accent) |
|
||
| base0E | `#e1a3ee` | violet — used for celebration (level-up, achievement unlock) |
|
||
| base0F | `#fb9fb1` | (alias) |
|
||
|
||
### Semantic assignments
|
||
|
||
- **CTA / Primary action**: brick red `#a54242`. Reserved for "Play," "New Game," "Save," "Resume," and the focus ring on selected cards. Never used decoratively. (Was cyan `#6fc2ef` before the 2026-05-08 swap.)
|
||
- **Valid-move / drag-target highlight**: lime `#acc267`. Reserved for in-game feedback only. Never appears in chrome.
|
||
- **Celebration**: lavender `#e1a3ee`. Used for level-up flashes, achievement unlock cards, and the daily-streak chip when the streak is active. Quiet otherwise.
|
||
- **Warning / soft alert**: gold `#ddb26f`. Used for "challenge expires in N minutes" chips, sync-pending status, and the daily-seed countdown.
|
||
- **Info**: teal `#12cfc0`. Used for neutral system toasts and the sync-connected indicator.
|
||
- **Error**: pink `#fb9fb1`. Used for sync conflict, server unreachable, invalid move shake.
|
||
|
||
## Suit Colors
|
||
|
||
**Two-color traditional mapping**, with mandatory color-blind support:
|
||
|
||
| Suit | Default | Color-blind mode | Glyph differentiation |
|
||
|---|---|---|---|
|
||
| Hearts | `#fb9fb1` (pink) | `#acc267` (lime) | Solid filled glyph |
|
||
| Diamonds | `#fb9fb1` (pink) | `#acc267` (lime) | **Outlined glyph (1.5px stroke)** |
|
||
| Spades | `#d0d0d0` (foreground) | `#d0d0d0` | Solid filled glyph |
|
||
| Clubs | `#d0d0d0` (foreground) | `#d0d0d0` | **Outlined glyph (1.5px stroke)** |
|
||
|
||
The outlined-glyph treatment is the **primary** differentiation mechanism. Color is supplementary. This means a player viewing the game on a monochrome display, or with severe red-green deficiency, can still distinguish all four suits without context. This is a hard requirement, not an optional setting.
|
||
|
||
The "color-blind mode" toggle in Settings only swaps red→lime; it does not turn the outlined glyphs on or off, because outlined glyphs are always on. (Was red→cyan before the 2026-05-08 primary-accent swap; CBM moved to lime to stay hue-distinct from the new red-family primary.)
|
||
|
||
## Typography
|
||
|
||
**Monospace-forward, dual-font system.**
|
||
|
||
- **JetBrains Mono** is used for: HUD (score, timer, moves), card rank/value text, all labels, all headlines, all numerals anywhere in the app, and any chip-style component. This is the dominant face.
|
||
- **Inter** is used only for: long-form body copy (Help screen, Settings descriptions, achievement tooltips, onboarding copy). It is the *exception*, not the default.
|
||
|
||
Weights: 400 regular, 500 medium for labels, 700 bold for HUD numbers and headlines. No 600 / no italics anywhere — the terminal aesthetic doesn't have them.
|
||
|
||
Letter spacing: tight (`-0.02em`) on HUD score for visual mass; wide (`+0.08em`) on uppercase labels for readability at 12px. Body uses default (0).
|
||
|
||
HUD numbers must use **tabular figures** (`font-feature-settings: 'tnum'`) so the timer and score don't reflow as digits change.
|
||
|
||
## Layout & Spacing
|
||
|
||
Optimized for **Android portrait, 390×844 (Pixel 6 baseline), API 34**.
|
||
|
||
- **Margins**: 16px (1rem) edge safety margin. *Tighter than the previous system's 24px.* Eighties palettes are dense by nature; over-padding fights the aesthetic.
|
||
- **Tableau**: 7-column layout, 32px (2rem) vertical card overlap. Tighter than before to fit a longer cascade on phone screens.
|
||
- **HUD position**: top of screen, in the system safe area. Bottom 64px holds the action bar (Undo / Hint / New Game / Auto-complete). Action bar is **always visible** in-game — no hover-fade — because there is no hover on touch.
|
||
- **Touch target minimum**: 48dp on all interactive elements. Cards in the tableau may be smaller visually but use a 48dp invisible hit area centered on the visible glyph.
|
||
|
||
## Elevation & Depth
|
||
|
||
Depth is created through **tonal layering and 1px outlines**, not blur shadows. (Synthwave-flat, not Material-soft.)
|
||
|
||
- **Level 0 (Background)**: the `#151515` base canvas.
|
||
- **Level 1 (Tableau slots, empty piles)**: 1px dashed outline in `#353535`. Empty foundations show a faint suit glyph at 12% opacity inside the outline.
|
||
- **Level 2 (Cards at rest)**: solid `#1a1a1a` fill, 1px solid border in the suit color (so the suit is detectable at a glance even if the card is partially obscured).
|
||
- **Level 3 (Active / dragged card)**: same border, but glow effect: 0 0 12px of `#a54242` at 40% opacity. **No scale transform** — flatness preserved. Z-index lifts above siblings.
|
||
- **Modals**: full-screen with backdrop `#151515` at 95% opacity (just enough to dim the table without blurring it). Modal panel is `#202020` with a 1px `#505050` border — like a terminal pane.
|
||
- **Toasts**: bottom of screen, `#202020` fill, 1px border in the toast's accent color (info=teal, warning=gold, error=pink, celebration=lavender). 16px monospaced caption.
|
||
|
||
No `box-shadow` is used anywhere. **All depth is achieved with borders and tonal value.** This is a hard constraint.
|
||
|
||
## Shapes
|
||
|
||
The shape language is **soft-rounded but tight**:
|
||
|
||
- **Cards**: `rounded-md` (8px) — slightly less rounded than the previous system's 16px to read more "technical."
|
||
- **Buttons / chips / inputs**: `rounded` (4px) default, `rounded-sm` (2px) for the smallest chips.
|
||
- **Modals / sheets**: `rounded-lg` (12px).
|
||
- **Avatars / circular indicators**: `rounded-full`.
|
||
- **Card-back pattern corners**: matches the card's `rounded-md`.
|
||
|
||
Selection highlights use a **2px inset stroke** in `#a54242` following the host shape's corner radius. Never an outer stroke — the outer stroke is reserved for the suit-color hairline.
|
||
|
||
## Motion
|
||
|
||
**Snappy, no spring.** All transitions use `ease-out` with a 120ms duration unless specified.
|
||
|
||
- Card lift (start drag): 80ms.
|
||
- Card place (drop): 120ms with a 16ms holdframe (no bounce).
|
||
- Modal enter: 200ms ease-out, fade + 8px translate-up.
|
||
- Modal exit: 120ms ease-in, fade only.
|
||
- Selection ring appear: 80ms.
|
||
- Win-summary stat reveal: 60ms each, staggered 40ms.
|
||
- HUD number tick: instant (no transition) — terminal counters don't ease.
|
||
|
||
**Optional CRT effect**: a 1-frame scanline sweep across the screen on game-state transitions (start, win, restart). User-toggleable in Settings. Off by default.
|
||
|
||
## Components
|
||
|
||
### Game Cards
|
||
|
||
Flat face design.
|
||
- Background: `#1a1a1a`
|
||
- Border: 1px solid in suit color (pink for hearts/diamonds, foreground gray for spades/clubs)
|
||
- Top-left: rank in JetBrains Mono Bold 18px + small suit glyph (10px)
|
||
- Bottom-right: large suit glyph (32px), upright (same orientation as the top-left small glyph — single-orientation digital play does not benefit from the traditional 180° inverted-corner indicator)
|
||
- Corner radius: 8px
|
||
- Suit differentiation: hearts and spades have **filled** glyphs; diamonds and clubs have **outlined** glyphs (1.5px stroke)
|
||
|
||
### Card Back ("Terminal" theme)
|
||
|
||
- Theme name: `"Terminal"`
|
||
- Author: `"Rusty Solitaire"`
|
||
- Background: `#151515`
|
||
- Pattern: horizontal scanlines at 2px pitch in `#1a1a1a` (1px line, 1px gap), full bleed
|
||
- Border: 1px solid `#353535`
|
||
- Top-left badge: a 12×16px solid `#a54242` block (the "terminal cursor"), 6px from the corner
|
||
- Bottom-right monogram: the characters `▌RS` in JetBrains Mono 12px, color `#505050`, 6px from the corner
|
||
- Corner radius: 8px (matches face)
|
||
|
||
### Primary Buttons
|
||
|
||
Solid `#a54242` fill, `#151515` text, JetBrains Mono Medium 14px uppercase with `+0.08em` tracking. 4px corner radius. Pressed state: darken to `#7a3030`. Disabled: `#353535` fill, `#505050` text.
|
||
|
||
### Secondary Buttons
|
||
|
||
Transparent fill, 1px `#505050` border, `#d0d0d0` text. Hover/press: border becomes `#a54242`, text becomes `#a54242`.
|
||
|
||
### HUD Chips
|
||
|
||
`#202020` fill, no border, 4px radius. Monospaced 16px text. Score chip pulses to `#acc267` for 200ms when score increases.
|
||
|
||
### Drag Targets
|
||
|
||
When a card is being dragged over a valid pile, the pile's empty-slot dashed outline becomes:
|
||
- Solid 1px in `#acc267`
|
||
- Plus a 0 0 8px outer glow in `#acc267` at 30% opacity
|
||
|
||
This is the *only* place glow effects appear in the system.
|
||
|
||
### Modals
|
||
|
||
Full-screen backdrop at 95% opacity. Centered panel: `#202020` fill, 1px `#505050` border, 12px corner radius. Title bar shows the screen name in monospaced 14px, color `#a0a0a0`, with a single `▌` cursor character prefix to reinforce the terminal pane motif.
|
||
|
||
### Navigation Bar
|
||
|
||
Fixed at the bottom of in-game screens. Height: 64px. `#202020` fill, 1px top border in `#353535`. Four icon buttons: Undo / Hint / New / Auto-complete. Icons: 24px, 1.5px stroke weight, color `#d0d0d0`. Active/pressed: icon color `#a54242`.
|
||
|
||
### Status / Sync Indicator
|
||
|
||
Top-right corner of the HUD: a 6px circular dot.
|
||
- Connected & synced: `#12cfc0`
|
||
- Pending: `#ddb26f` (pulsing 1.5s)
|
||
- Error: `#fb9fb1` (steady)
|
||
- Offline: `#505050`
|
||
|
||
## Accessibility
|
||
|
||
1. **Color-blind mode** (Settings → Gameplay): swaps red suits' default `#fb9fb1` for `#acc267` (lime). Outlined-glyph differentiation remains active in *all* modes.
|
||
2. **High-contrast mode** (Settings → Gameplay): boosts on-surface from `#d0d0d0` to `#f5f5f5`, outline from `#505050` to `#a0a0a0`, suit-red from `#fb9fb1` to `#ff8aa0`.
|
||
3. **Reduce-motion mode** (Settings → Gameplay): disables card-lift transition (instant z-lift), disables CRT scanline effect, disables the warning-chip pulse animation.
|
||
4. **Tabular figures** are mandatory for any number that updates live (timer, score, moves) so they don't reflow.
|
||
5. **Touch targets** are 48dp minimum even when the visual element is smaller.
|
||
6. **Text contrast**: all body text on background passes WCAG AA at minimum (`#d0d0d0` on `#151515` = 9.5:1; `#a0a0a0` on `#151515` = 5.7:1).
