docs: cut v0.20.0 — Terminal design system + Android persistence

Promotes the [Unreleased] section to [0.20.0] dated 2026-05-07
and opens a fresh empty [Unreleased]. The cycle's two through-
lines:

- **Terminal visual-identity port.** ui_theme token system
  (0d477ac) is load-bearing; downstream chrome migrations cover
  the modal scaffold, gameplay-feedback layer (ceec4fc), toasts
  with a new ToastVariant enum (a137607), table chrome (651f406),
  card chrome (d752870), splash cursor (cdcadda), and final
  hint-source / dest pairing (9891ae4). Card-face / suit / card-
  back palette intentionally NOT migrated — those track PNG
  artwork that hasn't been regenerated yet. The 24 Stitch-rendered
  mockups and design-system.md spec landed in fa7f98a.
- **Android persistence shim.** solitaire_data::data_dir
  routes through a per-platform shim (4b51e50) closing the
  CLAUDE.md §10 dirs::data_dir() = None pitfall on Android.
  Settings, stats, achievements, replays, game-state, time-attack
  sessions, and user themes now persist on a real APK.

Also closes three v0.19.0 punch-list candidates that landed
earlier in the cycle (pull_failure flake at 67c150b, smart-window-
size opt-out at e1b8766, Shareable badge at 9b065e5).

Tests: 1176 passing / 0 failing (six new this cycle: ui_theme
invariant guards, toast-variant-border-mapping, palette-tracking
guards on MARKER_VALID / HINT_PILE_HIGHLIGHT_COLOUR /
RIGHT_CLICK_HIGHLIGHT_COLOUR / toast-border distinctness).

SESSION_HANDOFF.md refreshed: HEAD pointer, test count, the
v0.20.0 changelog summary, the open punch list (Phase Android
runtime gaps, visual-identity follow-ups including the artwork
regeneration item), the updated design-direction box (was
Midnight Purple + Balatro yellow; now base16-eighties Terminal),
and a refreshed Resume Prompt offering A–F next-step options.

## [Unreleased]
Two threads in flight: closing the v0.19.0 punch list (settings opt-out
for the smart-default sizer, share-link discoverability, the last
async-pull test flake) and a new performance / portability arc (F3
diagnostics overlay landing first, then a working Android build
target via `cargo apk`). The Android build is the load-bearing
change — `solitaire_app` now compiles into both a desktop `bin` and
an Android `cdylib` from the same source tree, so subsequent work
can iterate on a phone or AVD without forking the codebase.
No threads in flight. v0.20.0 cut on 2026-05-07; CHANGELOG accumulates
the next cycle here.
## [0.20.0] — 2026-05-07
Two through-lines closed: a full **Android port** (build target,
first 54 MB APK, JNI-free per-app persistence shim) and the
**Terminal visual-identity port** that replaces the prior
Premium-Solitaire palette across every UI surface. The Android
arc opened in `fb8b2ac` (compile + APK), continued in `4b51e50`
(`solitaire_data::data_dir` shim closing the CLAUDE.md §10
`dirs::data_dir() = None` pitfall), and is functional end-to-end
on a real device — though the runtime artwork is still the legacy
white-card palette, and JNI ClipboardManager / keyring bridges
remain stubbed (matching v0.19.0's documented fallback behaviour).
The Terminal port lands as a top-down stack: the `ui_theme` token
API in `0d477ac` is load-bearing, and the rest of the cycle is
downstream applications (modal scaffold, gameplay-feedback,
toasts, table / card chrome, splash cursor, hint-highlight
pairing). The card faces and suit-pip palette are deliberately
NOT migrated — those track PNG artwork that hasn't been
regenerated yet, and swapping the fallback constants ahead of the
artwork would mix two visual systems on any code path where
image loading fails.
The 24 Stitch-rendered mockups in `docs/ui-mockups/` are now
in-tree (`fa7f98a`); future plugin work should diff against the
matching mockup before touching pixels.
Two threads from v0.19.0's punch list also closed in this cycle:
the pull-failure test flake (`67c150b`), the Settings opt-out for
the smart-default window sizer (`e1b8766`), and the share-link
discoverability surfacing (`9b065e5`). The remaining v0.19.0
candidate — the app-icon round — stays open.
### Added
- **`ui_theme` Terminal design-token system** (`0d477ac`). Single
source of truth for the engine's visual identity:
base16-eighties palette (cyan primary CTA, lime/lavender/gold/
teal/pink semantic accents), 5-rung type scale, 7-rung 4-multiple
spacing scale, 3-step radius, 14-rung z-index hierarchy, full
motion budget, and four invariant-pinning unit tests. Every
downstream port commit in this cycle reads from this module —
swapping the palette is now a one-file edit, not a hunt across
~50 plugin files. Card-shadow alphas pinned to 0 (Terminal
achieves depth via 1px borders + tonal layering, no
`box-shadow`); the rendering path is left intact so a future
palette can re-enable shadows without touching consumers.
- **`ToastVariant` enum + Terminal toast styling** (`a137607`).
Toasts now follow `docs/ui-mockups/design-system.md`: opaque
`BG_ELEVATED` fill, 1px accent border keyed off
`Info` / `Warning` / `Error` / `Celebration` variants, 18px
monospaced caption (`TYPE_BODY_LG`), bottom-anchored. All ten
call sites pass their semantic variant: achievement / level-up
/ XP / daily / weekly / challenge → Celebration (lavender);
goal-announcement / time-attack / settings volume / auto-complete
→ Info (teal). Two regression tests pin variant→border mapping
to the design tokens and require all four borders to be visually
distinct. Queued and immediate toasts use slightly different
bottom anchors (6 % vs. 14 %) so a celebration toast spawned
alongside a queued info banner layers above it.
- **Terminal cursor block on the splash overlay** (`cdcadda`).
The launch splash now renders the design system's signature
`▌` cyan (`ACCENT_PRIMARY`) glyph (96 px, hand-tuned literal)
above the wordmark, matching `docs/ui-mockups/splash-mobile.html`.
Cursor fades on the same per-frame alpha schedule as the title
and subtitle so the brand beat still dissolves as a single
layer. Did *not* pull in the mockup's full boot-loader treatment
(scanline overlay, ✓ check log, progress bar, ROOT@SOLITAIRE
prompt) — those are aesthetic features warranting their own
commit.
- **Terminal design-system spec + 24-mockup library** (`fa7f98a`).
`docs/ui-mockups/design-system.md` (palette, type scale, spacing
scale, motion budget, component library, accessibility notes —
color-blind toggle, high-contrast mode, glyph differentiation,
canonical `"Terminal"` card-back theme) and 24 Stitch-rendered
mockups (HTML + PNG): 12 redesigned existing screens, 1 desktop
home variant, 2 onboarding steps, and 9 missing-plugin screens
(splash, challenge, time-attack, weekly-goals, leaderboard,
sync, level-up, replay, radial-menu). The spec the rest of this
cycle ports against; future plugin work diffs here before
touching pixels.

that had drifted out of the cheat sheet are now listed.
### Changed
- **Gameplay-feedback colours route through Terminal state
tokens** (`ceec4fc`). Selection-highlight tints in
`selection_plugin` and the valid-drop marker tint in
`cursor_plugin` were hand-tuned RGB literals. Migrated to
semantic state tokens: keyboard-drag picking source →
`ACCENT_PRIMARY` (cyan focus); keyboard-drag lifted source →
`STATE_WARNING` (gold attention); destination → `STATE_SUCCESS`
(lime valid-move); `cursor_plugin::MARKER_VALID` →
`STATE_SUCCESS` at 0.55 α with a tracking test pinning its RGB
to the token. Three stale doc comments in `ui_modal` corrected
("loud yellow CTA" / "magenta secondary accent" → cyan /
lavender to match the actual token values).
- **`table_plugin` chrome migration to Terminal tokens** (`651f406`).
`marker_colour` promoted to module-level `pub const
PILE_MARKER_DEFAULT_COLOUR` so `cursor_plugin::MARKER_DEFAULT`
imports the const directly — replaces the prior
duplicated literal kept in sync only by doc comment with a
compile-enforced invariant. The empty-tableau "K" placeholder
text now uses `TEXT_PRIMARY` at 0.35 α; `HINT_PILE_HIGHLIGHT_COLOUR`
retuned from bright `srgb(1.0, 0.85, 0.1)` to the `STATE_WARNING`
token (`#ddb26f`) with a tracking test, and the existing "is
gold" character test loosened to fit the muted Terminal gold
while still rejecting non-warm colours.
- **`card_plugin` chrome migration to Terminal tokens** (`d752870`).
Drag-elevation shadow now sources its colour from
`CARD_SHADOW_COLOR` + `CARD_SHADOW_ALPHA_DRAG` so the Terminal
"no box-shadow" policy disables the stack shadow in lockstep
with the per-card shadows. `RIGHT_CLICK_HIGHLIGHT_COLOUR`
retuned from raw green to `STATE_SUCCESS` at 0.6 α with a
tracking test. The duplicated `PILE_MARKER_DEFAULT_COLOUR`
const dropped — this plugin now imports the promoted const
from `table_plugin`. Stock recycle "↺" text moved from raw
white-at-0.7-α to `TEXT_PRIMARY.with_alpha(0.7)`. Card-face /
suit / card-back palette constants were intentionally NOT
migrated (the runtime path renders PNG artwork that's still on
the previous "white card" palette).
- **Hint-source card tint matches the destination pile**
(`9891ae4`). `input_plugin`'s hint-source card tint moved from
raw bright-yellow `srgba(1.0, 1.0, 0.4, 1.0)` to `STATE_WARNING`,
so the source card and the destination pile (which already uses
`STATE_WARNING` via `HINT_PILE_HIGHLIGHT_COLOUR`) wear the same
attention colour as a coherent pair.
### Fixed
- **`solitaire_data::data_dir` shim closes the Android persistence
gap** (`4b51e50`). `dirs::data_dir()` returns `None` on Android,
which silently disabled every persistence path (settings, stats,
achievements, replays, game-state, time-attack sessions, user
themes). New `solitaire_data::platform::data_dir()` shim falls
through to `dirs::data_dir()` on desktop and returns the per-app
sandbox at `/data/data/com.solitairequest.app/files` on Android
— no JNI needed, since the package id is pinned in
`[package.metadata.android]`. Six call sites across
`solitaire_data` plus `solitaire_engine/assets/user_dir.rs`
migrated. CLAUDE.md §10 already flagged this as a known
pitfall; the shim pays it down at the one chokepoint instead
of per feature.
- **`card_shadow_params` test aligned with Terminal "no shadow"
intent** (`1d1543e`). The Terminal token system pinned both
`CARD_SHADOW_ALPHA_IDLE` and `CARD_SHADOW_ALPHA_DRAG` to 0.0,
which made the prior `drag_alpha > idle_alpha` assertion fail
(`0 > 0` is false). Loosened to `drag_alpha >= idle_alpha`
with a comment naming the new invariant: under Terminal both
are 0; under any future palette that re-enables shadows, drag
still must not be weaker than idle. The useful regression-guard
(catching an accidental swap of the two constants) is preserved.
