# Quickstart: Frontend Style Unification

## Purpose

Validate that frontend style unification is implemented consistently across targeted routes without functional regressions.

## Preconditions

- Feature branch: `001-unify-frontend-style`
- Frontend dependencies installed
- Application starts successfully in local environment
- Target routes available: dashboards, tasks, reports, settings

## Validation Flow

### 1) User Story 1 — Consistent Visual Foundation (P1)

1. Open each target route: dashboards, tasks, reports, settings.
2. Compare visual primitives:
   - typography hierarchy
   - spacing rhythm
   - card/container style
   - button variant consistency
3. Confirm no route has conflicting visual language for shared primitives.

**Expected Result**: Shared visual baseline appears coherent across all targeted routes.

### 2) User Story 2 — Unified Navigation and Page Shells (P2)

1. Navigate through at least three top-level routes.
2. Verify shell consistency:
   - page title placement
   - context/breadcrumb area behavior
   - primary/secondary action region location
   - content container alignment
3. Confirm transitions do not break orientation cues.

**Expected Result**: Page shell pattern is consistent and predictable across routes.

### 3) User Story 3 — Predictable Feedback and States (P3)

1. Trigger loading state on at least two routes.
2. Trigger empty state and error state where possible.
3. Trigger one success feedback event (save/update/apply action).
4. Compare message tone, placement, and recovery actions.

**Expected Result**: Loading/empty/error/success feedback follows one canonical pattern.

---

## Regression Safety Checks

1. Execute core functional flows on dashboards/tasks/reports/settings.
2. Confirm style unification did not remove or alter business-critical actions.
3. Confirm focus visibility and readability remain acceptable on updated UI areas.

**Expected Result**: No critical user flow regression and no accessibility degradation.
