+# Broker Accounts Page — Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Migrate broker-accounts page area to use `@moex-vibe/design-system` components.
+
+**Architecture:** Replace legacy CSS classes, inline styles, and shared/components with DS equivalents. Keep business logic and data layer unchanged. The hero gradient section is intentionally left as custom CSS.
+
+**Tech Stack:** React 18, MUI 6.5, `@moex-vibe/design-system` 0.1.0
+
+---
+
+## Files
+
+### Modify
+- `apps/frontend/src/pages/broker-accounts/ui/BrokerAccountsPage.tsx`
+- `apps/frontend/src/widgets/broker-accounts-summary/ui/BrokerAccountsSummary.tsx`
+- `apps/frontend/src/widgets/broker-account-card/ui/BrokerAccountCard.tsx`
+- `apps/frontend/src/shared/ui/broker-allocation-bar/BrokerAllocationBar.tsx`
+- `apps/frontend/src/styles.css` — удалить осиротевшие классы
+
+### No changes
+- Entity layer (`entities/broker-account/`, `entities/broker-position/`) — бизнес-логика не меняется
+- Shared formatters (`shared/lib/formatters.ts`) — используются для форматирования значений
+- Shared API layer (`shared/api/`) — не меняется
+
+---
+
+## Task 1: BrokerAllocationBar
+
+Replace inline HTML + CSS classes with `<Box>` + `<Text>`.
+
+- Empty: `<p className="broker-allocation-bar__empty">` → `<Text tone="muted">`
+- Track: `<div className="broker-allocation-bar__track">` → `<Box>` with `sx`
+- Segment: `<span style={{ width, background }}>` → `<Box>` with `sx`
+- Legend: `<ul>` / `<li>` → `<Box>` with `sx` flex layout
+- Swatch: `<span>` with inline style → `<Box>` with `sx`
+
+Segment width/background и swatch colors остаются как inline styles (dynamic per item, from ALLOCATION_CONFIG).
+
+## Task 2: BrokerAccountCard
+
+Replace legacy shared components and CSS with DS equivalents.
+
+- Skeleton block: `<SkeletonBlock>` → `<Skeleton>` from DS
+- Eyebrow: `<p className="broker-account-card__eyebrow">` → `<Text variant="label" tone="secondary">`
+- Title: `<h2 className="broker-account-card__title">` → `<Heading level={2}>`
+- Stat labels/values: `<span>` + `<strong>` → `<Text variant="label" tone="secondary">` + `<Text>`
+- Card wrapper: `<article className="broker-account-card broker-account-card--link">` → `<Surface>` with `component={Link}` or `<Box>` with `sx`
+- Error: `<article className="broker-account-card broker-account-card--error">` → `<Surface>` + `<Alert>` + `<Button>`
+- Card header layout: `<div className="broker-account-card__header">` → `<Box>` with flex `sx`
+- Card grid: `<div className="broker-account-card__grid">` → `<Box>` with grid `sx`
+- Card stat: `<div className="broker-account-card__stat">` → `<Box>` with grid `sx`
+
+## Task 3: BrokerAccountsSummary
+
+Replace skeleton, stats, typography with DS equivalents.
+
+- Skeleton: `<SkeletonBlock>` → `<Skeleton>`
+- Eyebrow: `<p className="broker-accounts-summary__eyebrow">` → `<Text variant="label" tone="secondary">`
+- Title (serif): keep as `<h2>` with CSS class (DS Heading не использует serif, теряется brand-стиль)
+- Status counts: `<span>` → `<Text>`
+- Currency label: `<p className="broker-accounts-summary__currency">` → `<Text variant="label" tone="secondary">`
+- Currency totals: `<strong className="broker-accounts-summary__total">` — keep as `<strong>` with CSS (serif)
+- Metrics: `<dl>`/`<dt>`/`<dd>` → `<Metric>` for each stat
+- Metric layout grid: `<div className="broker-accounts-summary__metrics">` → `<Box>` with grid `sx`
+
+The hero section (`broker-accounts-summary__hero`) keeps its CSS classes — custom gradient, not replaceable.
+
+## Task 4: BrokerAccountsPage
+
+Replace page-level layout, typography, empty/error states.
+
+- Page grid: `<div className="broker-accounts-page">` → `<Box>` with grid `sx`
+- Header: `<header className="broker-accounts-page__header">` → `<Box>` with flex `sx`
+- Eyebrow: `<p className="broker-accounts-page__eyebrow">` → `<Text variant="label" tone="secondary">`
+- Title: `<h1 className="broker-accounts-page__title">` → `<Heading level={1}>` (note: serif lost)
+- Caption: `<p className="broker-accounts-page__caption">` → `<Text tone="secondary">`
+- Cards grid: `<div className="broker-accounts-page__cards">` → `<Box>` with grid `sx`
+- Empty: `<section className="broker-accounts-empty">` → `<EmptyState>`
+- Error: `<p style={{ color: ... }}>` → `<Text tone="negative">`
+
+## Task 5: Clean up orphaned CSS
+
+After all migrations, remove from `styles.css`:
+- `.broker-accounts-page`, `.broker-accounts-page__header`, `.broker-accounts-page__eyebrow`, `.broker-accounts-page__title`, `.broker-accounts-page__caption`, `.broker-accounts-page__cards`
+- `.broker-accounts-empty`
+- `.broker-account-card`, `.broker-account-card--link`, `.broker-account-card--loading`, `.broker-account-card--error`, `.broker-account-card__header`, `.broker-account-card__eyebrow`, `.broker-account-card__title`, `.broker-account-card__opened`, `.broker-account-card__grid`, `.broker-account-card__stat`, `.broker-account-card__stat--wide`, `.broker-account-card__alert`, `.broker-account-card__retry`
+- `.broker-allocation-bar`, `.broker-allocation-bar__track`, `.broker-allocation-bar__segment`, `.broker-allocation-bar__legend`, `.broker-allocation-bar__legend-item`, `.broker-allocation-bar__swatch`, `.broker-allocation-bar__empty`
+- `.broker-accounts-summary__eyebrow`, `.broker-accounts-summary__currency`, `.broker-accounts-summary__total`, `.broker-accounts-summary__metrics`, `.broker-accounts-summary__metric`
+- `.broker-accounts-summary__currency-card` and its children (header, currency, total, metrics, metric)
+- `.broker-accounts-summary__status` and children
+
+Keep: `.broker-accounts-summary`, `.broker-accounts-summary--loading`, `.broker-accounts-summary__hero`, `.broker-accounts-summary__title` (serif), shared `.broker-accounts-summary__eyebrow` shared rule (hero-specific), `.broker-accounts-summary__currency-grid`

+# Broker Accounts Page — Design System Migration
+
+## Status
+
+Draft
+
+## Goal
+
+Мигрировать BrokerAccountsPage, BrokerAccountsSummary, BrokerAccountCard и BrokerAllocationBar на компоненты `@moex-vibe/design-system`, заменив legacy CSS и inline-стили на DS-компоненты и MUI layout utilities.
+
+## Scope
+
+- `apps/frontend/src/pages/broker-accounts/ui/BrokerAccountsPage.tsx`
+- `apps/frontend/src/widgets/broker-accounts-summary/ui/BrokerAccountsSummary.tsx`
+- `apps/frontend/src/widgets/broker-account-card/ui/BrokerAccountCard.tsx`
+- `apps/frontend/src/shared/ui/broker-allocation-bar/BrokerAllocationBar.tsx`
+- `apps/frontend/src/styles.css` — удалить CSS-классы и переменные, оставшиеся без потребителей
+
+### DS-компоненты для внедрения
+
+| HTML / legacy | DS-компонент |
+|-------------|-------------|
+| `<h1>`, `<h2>` | `<Heading>` |
+| `<p>`, `<span>` label | `<Text>` |
+| `<span>` eyebrow | `<Text variant="label" tone="secondary">` |
+| `<dl>`/`<dt>`/`<dd>` stat | `<Metric>` |
+| `div.broker-accounts-empty` | `<EmptyState>` |
+| `div.broker-account-card__alert` + button | `<Alert severity="error">` + `<Button variant="primary">` |
+| `div.broker-accounts-summary__hero` title/text | `<Heading>` + `<Text>` |
+| `.broker-account-card` card | `<Surface>` or `<Card>` |
+| `<SkeletonBlock>` | `<Skeleton>` from DS |
+| `div.broker-accounts-page` layout | `<Box>` with `sx` |
+| `div.broker-accounts-page__header` | `<Box>` with flex |
+| `div.broker-accounts-page__cards` | `<Box>` with grid |
+| `p.broker-allocation-bar__empty` | `<Text tone="muted">` |
+
+## Out of scope
+
+- Hero gradient section visual identity (too custom, no DS equivalent)
+- Serif font family on titles (DS uses Inter)
+- Allocation bar colors from ALLOCATION_CONFIG (business config, not tokens)
+- Добавление новых тестов (entity-тесты существуют, page-тесты — новая фича)
+- Рекламные/декоративные элементы (градиенты, кастомные скругления)
+
+## Acceptance Criteria
+
+- [ ] BrokerAccountsPage не содержит CSS-классов из styles.css; `<h1>` / `<p>` заменены на `<Heading>` / `<Text>`
+- [ ] BrokerAccountsPage empty state использует `<EmptyState>`, error — `<Text tone="negative">`
+- [ ] BrokerAccountsSummary skeleton использует DS `<Skeleton>`, stats используют `<Metric>`, eyebrow/title используют `<Text>`/`<Heading>`
+- [ ] BrokerAccountCard skeleton/error/success используют DS `<Skeleton>`, `<Alert>`, `<Button>`, `<Heading>`, `<Text>`, `<Metric>`, `<Surface>`
+- [ ] BrokerAllocationBar использует `<Box>` + `<Text>` вместо div/p с CSS-классами
+- [ ] ESLint allowlist не нарушен
+- [ ] `npm run test:frontend && npm run lint -w apps/frontend && npm run build:frontend` проходят
+- [ ] CSS-классы, оставшиеся без потребителей, удалены из styles.css
