# This is NOT the Next.js you know

This version has breaking changes — APIs, conventions, and file structure may all differ from your training data. Read the relevant guide in `node_modules/next/dist/docs/` (resolved from this file's directory; in monorepos the `next` package may not be visible from the repo root) before writing any code. Heed deprecation notices.

This block is written and re-added by `next dev` — verify at `node_modules/next/dist/server/lib/generate-agent-files.js`. Removing it from a diff only re-creates the uncommitted change; committing it with your work keeps the tree clean.

Astryx v0.2.0 · 154 components
CLI: run every command as `npx astryx <cmd>` (shown below as `astryx ...`).

SETUP (once, in your app entry e.g. main.tsx) — without these, components render unstyled:
  import "@astryxdesign/core/reset.css";
  import "@astryxdesign/core/astryx.css";

WORKFLOW — discover, don't guess. Before writing UI:
1. `astryx build "<idea>"` — START HERE: returns a kit (closest [page] + [block]s + [component]s). No args = full playbook.
2. `astryx template <name> [--skeleton]` — scaffold the [page]/[block]s it named, or study their layout. Templates are reference code.
3. `astryx component <Name>` — props + examples for every component you use.

RULES:
- No <div> — components do all layout/spacing. Full page → AppShell; sidebar nav → SideNav.
- Frame first: pick the shell (AppShell / Layout+LayoutPanel) and budget regions in px BEFORE writing content (`astryx docs layout`).
- Dense data = rows (Table, List/Item) edge-to-edge — never Card-wrapped list items. Card = dashboard widgets, galleries, settings groups only.
- Status → StatusDot/Token; Badge only for counts and enumerated states, never decoration.
- Custom styling: component props first; else Tailwind utilities backed by tokens (bg-surface, text-primary, rounded-lg) via tailwind-theme.css. No raw hex/px.
- Tokens for every value (`astryx docs tokens`). Brand/accent via `astryx theme` — never override --color-* in :root.
- SELF-CHECK before you finish: re-read the file and replace any style={{…}}, raw <div>/<span> layout, imported .css/@apply, or hardcoded/arbitrary value (e.g. bg-[#fff], p-[13px]) with the component or a token-backed utility. If unsure a component/prop exists, run `astryx component <Name>` / `astryx search "<thing>"`; don't hand-roll CSS.

MORE CLI:
  search "<query>"   find any component / hook / doc / template / block
  component --list   154 components by category
  template --list    page + block recipes
  docs <topic>       color, elevation, icons, illustrations, internationalization, layout, migration, motion, principles, shape, spacing, styling, theme, tokens, typography
  swizzle <Name>     eject component source for deep customization
  upgrade --apply    run after any @astryxdesign/core bump

# Loyaly Merchant Dashboard — project rules

## Toolchain
- **Node 22 is required** (`.nvmrc` → 22.23.1). The astryx CLI hard-fails on Node 20.
  `nvm use` before running any `npx astryx` command or `npm run theme:build`.
- Dev server runs on **port 3100** (`lytsup-site` owns 3000).

## Theme
- All design values live in `src/theme/loyalyTheme.ts`. Edit that, then run
  `npm run theme:build`, then **commit the generated** `src/theme/loyaly.{css,js,d.ts,variants.d.ts}`.
- `theme:build` is deliberately NOT wired to `prebuild` — it would break `npm run build` on Node 20.
- Import the theme from **`@/theme`**, never `@/theme/loyaly` directly. `@/theme` re-attaches
  the Lucide icon registry, which `astryx theme build` cannot serialise (icons are React
  components). Skipping it silently degrades every `<Icon>` to Astryx's default glyph set.
- `globals.css` imports `../theme/loyaly.css`, NOT `@astryxdesign/theme-neutral/theme.css`.
  Astryx theme CSS is `@scope`-gated on the theme *name*, so neutral's rules match nothing
  under `[data-astryx-theme="loyaly"]`.

## The monochrome rule
Gray is the accent. The **only** colour permitted is semantic: success, warning, error.
- Astryx's categorical hues (blue/cyan/teal/purple/pink/orange) are aliased to gray in
  `aliasHueToGray()`. green/red/yellow deliberately keep hue — Banner's semantic statuses
  resolve *through* those hue tokens.
- Some neutral-theme component styles hardcode colour instead of reading a token
  (`badge variant:info`, `progressbar variant:accent`). Those need an explicit `components`
  override; `aliasHueToGray()` cannot reach them.
- `/tokens` (dev-only route) is the audit page. After any theme change, load it and run the
  chromatic sweep in the browser console — it should report **0** non-semantic colour nodes.

## The two brand accents (exception to the above)
Store intelligence carries exactly **two** non-semantic hues, and nothing else may add a third.

| | token | light | dark | used for |
|---|---|---|---|---|
| warm | `--color-brand-warm` | `#F4C430` | `#F4C430` | brand, rewards, the activities a merchant runs |
| cool | `--color-brand-cool` | `#7C3AED` | `#A78BFA` | analytics, journeys, AI insight |

- Defined in `src/app/globals.css` in a Tailwind `@theme` block, **not** in `loyalyTheme.ts`.
  They are not Astryx tokens: no component variant resolves through them, and putting them in
  the theme would let Badge/Banner pick them up as part of the semantic language.
- Three slots per hue. `-ink` is the readable one for text and icons (light mode darkens warm
  to `#8A6300`; raw `#F4C430` on white is ~1.7:1). `-soft` is an icon-chip tint only — never a
  card background. The base is for non-text marks: chart fills, dots, bars.
- `src/shared/utils/accent.ts` is the only place a hue becomes a class name. Feature files use
  `ACCENT[accent].ink` / `.soft`, never `text-brand-warm-ink` by hand.
- Charts stay monochrome by default. `CHART.brand.{warm,cool}` is opt-in per series and is used
  on exactly two charts (dashboard Footfall = cool, Revenue = warm). Never make it a ramp
  default — `Sparkline` reads `seriesAt(0)`, so that would turn every KPI card's trend line.
- An activity's accent travels on its API payload (`ActivityMetric.accent`), not from grid
  position, so an activity is the same colour on every screen.

## Attribution is estimated — say so
Everything downstream of `ActivityImpact.customers` (repeat visits, purchases, revenue) is
**modelled**, not measured. No purchase is joined to a specific spin, selfie or challenge.

- The field is `attributedRevenueInr`, never `revenueInr`, and every payload carries
  `attribution: 'estimated' | 'observed'`.
- Copy says *attributed*. Never "generated", "earned" or "drove". A merchant who reads
  "Selfie generated ₹3.4L" and spends against it is the failure this rule prevents.
- `<AttributionNote basis={…} />` sits in the header of every panel that shows an attributed
  figure, and renders **nothing** when the basis is `'observed'` — so a real attribution
  backend retires the disclosure with no copy edit. Read the basis off the payload, never
  hardcode it.
- The single sentence lives in `ATTRIBUTION_NOTE` (types/intelligence.ts) so three panels
  cannot drift.

## Dashboard supporting analytics are collapsed by default
The six preserved supporting panels (conversion pair, peak hours, reward usage, period rollup,
store comparison) sit inside a `Collapsible`, closed by default, state in
`loyaly.dashboard.supporting-analytics`. Expanded they add ~1,700px desktop / ~3,100px mobile
and push "What needs your attention" — the only actionable section — to 81% of the scroll.
They are evidence, not the finding. Do not re-expand by default; do not delete them either.

## Known upstream issues (Astryx 0.2.0)
- **`useEntryAnimation` breaks SSR hydration.** Its source assumes `'use client'` modules never
  run on the server; in the App Router they do. Any `FieldStatus` (i.e. `TextInput`/`TextArea`
  `status={...}`) present at *initial paint* renders without the slide-down class on the server
  and with it on the client → an unpatchable class mismatch. Setting status on blur/submit
  (the normal path) is unaffected. Don't server-render a field that already has a status.
- Component keys in `defineTheme({components})` are inconsistently cased: `text-input` but
  `progressbar`. The CLI warns on unknown keys, but that warning is **not** reliable in
  either direction:
  - A *misspelled* key (`textinput`) is dropped silently — the CSS is never emitted.
  - A key the CLI doesn't know but Astryx *does* use (`table-cell`, `table-header-cell`)
    warns yet still emits correctly.
  So never trust the warning alone. After any `components` change, grep the generated
  `src/theme/loyaly.css` for the rule, then confirm the computed style in the browser.
  Valid targets are whatever `themeProps('...')` is called with in `dist/<Component>/*.js`.
- `StyleOverrides` supports structural pseudo-classes, not just interaction ones —
  `':first-child'` emits correctly (used for the table first-column lead-in).

## Deployment — never ship `.next/` wholesale
This filled the production disk and took the server down once. A working tree's `.next/`
reaches **2+ GB**, but almost none of it is runtime state:

| path | size (typical) | ships? |
|---|---|---|
| `.next/dev` | 1.8 GB | **no** — Turbopack dev-server cache from `npm run dev` |
| `.next/cache` | 120–160 MB | **no** — incremental build cache, build host only |
| `.next/server`, `types`, `trace` | ~24 MB | **no** — inputs to the standalone trace, not read at runtime |
| `.next/standalone` | 54 MB | **yes** — server.js + traced node_modules |
| `.next/static` | 3 MB | **yes** — hashed client assets (nginx serves at `/_next/static/`) |
| `public` | 344 KB | **yes** |

Those last three are the entire payload: **~55 MB unpacked, 18 MB gzipped.**
- Non-Docker deploy: `npm run bundle` → `dist/loyaly-mer-login.tar.gz`. Never `scp -r .next`.
- Docker: `.dockerignore` excludes `node_modules` and `.next`. **Do not delete it** — without
  it `COPY . .` pushes the host's 2 GB `.next` and 639 MB `node_modules` into the build
  context, including darwin-arm64 sharp binaries that are wrong for Alpine.
- `npm run clean` drops `.next`, `dist` and the tsbuildinfo when the tree gets heavy.

**`CI_BUILD=1` in container builds.** Next 16.3 enables `turbopackFileSystemCacheForBuild`
by default; it writes 117 MB to `.next/cache` that only pays off when that directory is
restored between builds. Docker/Dokploy starts from a clean layer every time, so it is
written and never read. The Dockerfile sets `CI_BUILD=1`, which flips the flag off in
`next.config.ts`: **~20% less build CPU** (32s vs 40–43s measured) and `.next` drops
202 MB → 86 MB. Leave it unset locally — repeat `npm run build` there does reuse the cache.
It changes no output: the deployable payload is 58 MB either way.

## Conventions
- Follow the Astryx rules above: no raw `<div>` for layout, no hardcoded hex/px, component
  props first then token-backed Tailwind utilities.
- `src/lib/icons.ts` is the single icon map. Only the 26 semantic names resolve via
  `<Icon icon="search"/>`; everything else is `<Icon icon={ICONS.stores}/>`. Never import a
  lucide icon directly into a feature file.

## Settings spacing contract
Every Settings screen renders inside `src/features/settings/SettingsPage.tsx`. Do not add
page padding in an individual settings page — change the container instead.

| | value | why |
|---|---|---|
| Horizontal | 32px (`paddingInline={8}`) | clears the sub-nav and the Loyaly AI rail |
| Top | 32px (`paddingBlock={8}`) | title never touches the header |
| Bottom | 48px (`className="pb-12"`) | last card is never flush to the fold |
| Header → body | 32px (`gap={8}`) | title block reads as its own layer |
| Between body blocks | 24px (`gap={6}`) | cards, tables, toolbars |

`SpacingStep` stops at 10 (40px) and Stack has no `paddingBlockEnd`, which is why the 48px
bottom goes through the Tailwind bridge — `pb-12` still resolves to `--spacing-12`, so no
raw pixel value enters the codebase. It sits in the `utilities` layer, which the cascade
puts after `astryx-base`, so it wins over `paddingBlock` without `!important`.

Card padding (24px) and table cell padding (12px, 20px first-column lead-in) are set once
in `loyalyTheme.ts` so every module agrees — not per page.
