## Description

Rebuilds an app screen by screen from the recon map: app shell first, then the core flow as a vertical slice, then every screen with all its states, ticking off the feature matrix as it goes. Writes every line fresh, never the original's code, assets or copy. Use when the user says "build the clone", "build screen S07", "start building", "rebuild this screen", "implement the booking page", or after /replica-design.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# replica-build

Reads `replica/recon.md`, `replica/architecture.md`, `replica/design/`.
Updates `replica/features.csv` (the `clone` column) and keeps
`replica/build-log.md`.

## The rules

- **Clean room.** Every line of code is written here, from the recon map and
  the specs. Never paste the original's HTML, CSS, JavaScript, SVGs or
  images, never load anything from its domain or CDN, never "view source and
  adapt".
- **Your words.** Write every label, button, empty state and email fresh.
  Matching what a button does is parity. Matching its sentence is copying.
- **Tokens only.** No raw hex or pixel values in components. If a value is
  missing, add it to the tokens.

## Step 1: the shell

Routing for every screen in the inventory (stub pages are fine), the layout
(nav, header, sidebar), tokens wired in, the primitives from replica-design,
and seed data so screens have something real to show. Commit.

## Step 2: the vertical slice

The core loop from the recon map, end to end, before anything else. For a
booking app: create an event type, open the public page, book a slot, see it
on the dashboard. Ugly is fine. Working is the point. If replica-backend has
not run yet, use the seed data and a fake data layer with the same function
signatures, so swapping in the real one changes no screen code.

## Step 3: screen by screen

Work in the order of `architecture.md`. For each screen:
