+# Changelog
+
+## Unreleased
+
+- **Foundation tokens now follow the design system / official theme.** `BullTheme`
+  is the full 1:1 `AppColors` mirror (all ~40 fields, official names); `BullRadius`
+  adopts the design scale (`0/4/8/12/16/28/32/999`) and `BullSpacing` the design
+  scale (`0/4/8/12/16/24/32/48/64`); `BullTextStyles` is **removed** — type comes
+  from the Material `TextTheme` (`AppFonts`). All `Bull*` components were remapped
+  (`context.bull.red→primary`, `btc→onTertiary`, `muted→textMuted`,
+  `card→cardBackground`, radius/spacing → new scales). Tokens are fixed (not
+  screen-scaled); responsiveness is a layout concern.
+- `BullSwipeAction` action panel wrapped in `FittedBox(scaleDown)` so the
+  icon+label never overflows a short row.
+
+- Expand `BullTheme` with `secondary`, `onSecondary`, `secondaryFixedDim`,
+  `border`, `onSurface`, `onSurfaceVariant` and `scrim` (plus `copyWith`/`lerp`
+  and the app-side `_bullThemeFrom` builder), sourced from `AppColors`.
+- Duplicate the dependency-clean set of `lib/core/widgets/**` as `Bull*`
+  copies: `BullInputText`, `BullPasteInput`, `BullDropdown`,
+  `BullSelectableList`, `BullDialPad`, `BullAmountInputFormatter`,
+  `BullLowerCaseTextFormatter`, `BullCountdown`, `BullFadingLinearProgress`,
+  `BullScrollableColumn`, `BullStackedPage`, `BullPullableBody`,
+  `BullOptionsTag`, `BullInfoCard`, `BullPriceCard`, `BullBackupOptionCard`,
+  `BullBorderedTile`, `BullTransactionDirectionBadge`, `BullSettingsEntryItem`,
+  `BullTabMenuVerticalButton`, `BullViewerActionButton`. See the README
+  "Components" / "Not yet migrated" tables.
+- Duplicate the remaining dependency-clean widgets: `BullDetailsTable` +
+  `BullDetailsTableItem` (`DetailsTable` / `DetailsTableItem`),
+  `BullPickerSheet` (`BBPickerSheet`) and `BullInstructionsSheet`
+  (`InstructionsBottomSheet`). No new `BullTheme` fields were required — they
+  reuse the existing `surface`, `border`, `onSurface`, `red` and `text` colours.
+- Widget tests for `BullDropdown`, `BullCountdown` and `BullDialPad`.
+
+## 0.0.1
+
+- Seed the `bull_ui` design-system package: `BullTheme` (`ThemeExtension`),
+  `BullRadius`/`BullSpacing`/`BullTextStyles`/`BullIcon` tokens, and the first
+  set of `Bull*` components for the Coins view (issue #760).

+# bull_ui
+
+The Bull Bitcoin design-system component library — the go-forward source of truth for
+shared UI primitives. It is the first melos workspace member (`packages/bull_ui`).
+
+Every public widget is prefixed `Bull*` (e.g. `BullText`, `BullButton`, `BullScaffold`).
+This prefix is provenance: **`BB*` = legacy widgets in `lib/core/widgets`, `Bull*` = here**.
+The two coexist during the incremental migration; `BB*` originals are retired
+feature-by-feature in later scoped PRs as usages migrate. Nothing is moved or renamed —
+`bull_ui` components are duplicated copies, so existing app code is untouched.
+
+## Theme injection
+
+`bull_ui` is **brightness-agnostic** and never hardcodes a colour. The app injects the
+palette: it builds a `BullTheme` (a `ThemeExtension`) from `AppColors.light` and another
+from `AppColors.dark`, and registers each on the matching `ThemeData` via `extensions:`.
+Components read colours through `context.bull` (e.g. `context.bull.primary`). `BullTheme` is a
+**1:1 mirror of the app's `AppColors`** — same field names — so the app wires every field through
+without translation. Derived fills use `tokenColor.withValues(alpha: …)` so they adapt to both
+light and dark automatically.
+
+## Foundation tokens
+
+Brightness-invariant tokens are static consts, from the design system:
+
+- **`BullRadius`** — `zero·xs·sm·md·lg·xl·xxl·full` = `0·4·8·12·16·28·32·999`.
+- **`BullSpacing`** — `zero·xxs·xs·sm·md·lg·xl·xxl·xxxl` = `0·4·8·12·16·24·32·48·64`.
+- **Type** comes from the Material `TextTheme` (`Theme.of(context).textTheme`, sourced from
+  `AppFonts`) — there is no separate text-token class.
+- **Icons** via `BullIcon(BullIcons.…)`.
+
+**Tokens are fixed — never scaled by screen size.** Responsiveness is a *layout* concern
+(breakpoints, `LayoutBuilder`, max-width wrappers, adaptive columns), not a token concern; text
+already honours the user's `MediaQuery.textScaler`. The catalogue (`packages/bull_ui_catalogue`)
+has a `Foundation/` section showcasing colours, radius, spacing and the text scale.
+
+Fonts (Golos Text, Bebas Neue) are declared at the app root and resolve by family name
+across the workspace — `bull_ui` references them by name and does not re-ship the `.ttf`s.
+
+## Import surface
+
+Consumers import a single barrel:
+
+```dart
+import 'package:bull_ui/bull_ui.dart';
+```
+
+It re-exports a curated `show` list of `package:flutter/widgets.dart` layout/foundation
+symbols plus every `Bull*` component and the theme. Internals live under `lib/src/`.
+
+## Components
+
+Duplicated from `lib/core/widgets/**` as dependency-clean `Bull*` copies (the
+`BB*`/core originals are left untouched). Grouped by barrel category:
+
+**Buttons** — `BullButton`, `BullToolButton`, `BullTabMenuVerticalButton`
+(`TabMenuVerticalButton`), `BullViewerActionButton` (`ViewerActionButton`).
+
+**Inputs** — `BullCheckbox`, `BullFilterChip`, `BullInputText` (`BBInputText`),
+`BullPasteInput` (`PasteInput`), `BullDropdown` (`BBDropdown`),
+`BullSelectableList` + `BullSelectableListItem` (`SelectableList`),
+`BullDialPad` (`DialPad`), `BullAmountInputFormatter` (`AmountInputFormatter`),
+`BullLowerCaseTextFormatter` (`LowerCaseTextFormatter`).
+
+**Controls** — `BullSegmented`, `BullSwipeAction`, `BullSwitch` (`BBSwitch`).
+
+**Feedback** — `BullRefreshIndicator` (`BBRefreshIndicator`), `BullShimmerBox`/
+`BullShimmerLine`, `BullSnackBar`, `BullCountdown` (`Countdown`),
+`BullFadingLinearProgress` (`FadingLinearProgress`).
+
+**Layout** — `BullScrollableColumn` (`ScrollableColumn`), `BullStackedPage`
+(`StackedPage`), `BullPullableBody` (`BBPullableBody`).
+
+**Data display** — `BullAddressText`, `BullBadge`, `BullInfoBar`,
+`BullLabelChip`, `BullStatTile`, `BullText` (`BBText`), `BullOptionsTag`
+(`OptionsTag`), `BullInfoCard` (`InfoCard`), `BullPriceCard` (`PriceCard`),
+`BullBackupOptionCard` (`BackupOptionCard`), `BullBorderedTile`
+(`BorderedTappableTile`), `BullTransactionDirectionBadge`
+(`TransactionDirectionBadge`), `BullSettingsEntryItem` (`SettingsEntryItem`),
+`BullDetailsTable` + `BullDetailsTableItem` (`DetailsTable` / `DetailsTableItem`).
+
+**Overlays** — `BullBottomSheet`, `BullDialog`, `BullPickerSheet`
+(`BBPickerSheet`), `BullInstructionsSheet` (`InstructionsBottomSheet`).
+
+**Chrome** — `BullScaffold`, `BullTopBar`, `BullSelectionActionBar`.
+
+## Not yet migrated (needs dep abstraction)
+
+These `core/widgets` widgets still reach into `package:bb_mobile/*` (or otherwise
+can't preserve their public API on top of the clean kit) and are **deferred**
+until the dependency is abstracted out of the widget:
+
+| Widget | Blocker |
+| --- | --- |
+| `MultiTapTrigger` | `package:bb_mobile/core/widgets/snackbar_utils.dart` — its public `tapsReachedMessageTextColor` / `tapsReachedMessageBackgroundColor` API can't be honoured by `BullSnackBar.show` (String-only), so migrating would lose API. |
+| `CopyInput`, `BBKeyboardActions` | depend on `package:bb_mobile/*` localization / app utils. |
+| `BBButton` (`buttons/button.dart`) | already superseded by `BullButton`; not a 1:1 copy. |
+| Cards: `ActionCard`, `AutoswapWarningCard`, `BackupCard`, `BalanceCard`, `ProviderCart`, `WalletCard` | `package:bb_mobile/*` (router, l10n, feature models, `Assets`). |
+| `BBKeyboardActions` | needs `package:keyboard_actions/keyboard_actions.dart`, not declared in `bull_ui/pubspec.yaml` (no new deps rule). |
+| Bottom sheets: `AdvancedOptions`, `ComingSoon`, `Warning`, `NotLoggedIn`, `DeleteAccount*`, `Logout*`, `TranslationWarning` | `context.loc` localization and/or `package:bb_mobile/*` router & assets. |
+| Cards: `AutoswapWarningCard` | `context.loc` (`autoswapWarningCard*` strings) + `context.font` from `package:bb_mobile/core/utils/build_context_x.dart`. |
+| Loading: `ProgressScreen`, `StatusScreen` | `ProgressScreen` imports `package:bb_mobile/generated/flutter_gen/assets.gen.dart`; `StatusScreen` uses `context.loc` + `BBButton`. |
+| Viewers: `AddressViewer`, `TransactionViewer`, `InvoiceViewer`, `LogViewer`, `QrScanner`, `NfcScanner`, `ShareLogs`, `Bip85Derivation`, `MnemonicWidget`, `CoinSelectionBottomSheet`, `AppLanguagePicker`, `BackupSuccessScreen`, `PriceInput`, `TransactionsByDayList`, `BalanceRow`, `RecoverbullVaultProviderSelector` | `package:bb_mobile/*` (entities, l10n, assets, feature blocs). |
