chore: add WhatsApp® on first mention across user-facing surfaces
Per Meta's brand-use guidance for third-party products, the registered
trademark symbol (®) should appear on the FIRST mention of "WhatsApp"
on each user-facing page. Subsequent mentions on the same page are
left plain.

Surfaces touched (one-per-page first mention):
- Landing hero badge ("Built on the official WhatsApp® Business API").
- src/lib/seo/site-config.ts: SITE_TAGLINE and SITE_DESCRIPTION
  (rendered into <title> and <meta description> on every page).
- src/app/opengraph-image.tsx: hero text in social-share image.
- Settings, Inbox connection banner, Automations page subtitle.
- README.md tagline.
- All public docs pages (docs/README.md, docs/whatsapp-setup.md,
  docs/getting-started.md, docs/supabase-setup.md,
  docs/environment-variables.md, docs/deployment-hostinger.md,
  docs/automations-and-cron.md, docs/architecture.md,
  docs/troubleshooting.md).

Out of scope: SITE_KEYWORDS (the meta-keywords array isn't
user-rendered text — putting ® on every keyword would look broken in
the meta tag).

# Troubleshooting
The greatest hits. If your problem is not here, open an issue at
<https://github.com/ArnasDon/wacrm/issues>.
## Build-time
### `Error: ENCRYPTION_KEY must be 64 hex chars`
`ENCRYPTION_KEY` is missing or not the right length. Generate one:
```bash
node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"
```
Put the output into `.env.local` / your production env.
### `Error: supabaseUrl is required`
`NEXT_PUBLIC_SUPABASE_URL` or `NEXT_PUBLIC_SUPABASE_ANON_KEY` is not set
at build time. On Hostinger / any Node host, make sure the env vars are
exported **before** `npm run build` runs.
### Next.js complains about missing framework docs
The repo's `AGENTS.md` pins contributors to the docs bundled in
`node_modules/next/dist/docs/` — that notice is for humans editing the
code, it does not affect your build.
## Auth
### Sign-up succeeds but the confirmation email never arrives
In Supabase → **Authentication → Providers → Email**, either:
- Configure a custom SMTP provider (recommended for production), or
- Temporarily turn off **Confirm email** while testing.
### Password-reset links point at `localhost:3000` in production
Set `NEXT_PUBLIC_SITE_URL` **and** add the same origin to Supabase →
**Authentication → URL Configuration → Redirect URLs**.
## WhatsApp®
### Webhook verification fails in Meta
- The **verify token** in Meta must match exactly what you saved in
**Settings → WhatsApp** inside WaCRM.
- The callback URL must be reachable without auth. Test it yourself:
`curl 'https://crm.example.com/api/whatsapp/webhook?hub.mode=subscribe&hub.verify_token=<token>&hub.challenge=test'`
should return `test`.
- `META_APP_SECRET` must be set on the deployment (it's required —
without it, every inbound POST gets a 401). If it's set but wrong,
you'll also see 401s for every POST while the initial subscribe
handshake (which doesn't use it) works. Double-check the value
matches Meta → App Settings → Basic → App Secret exactly.
### Messages go out but nothing comes in
1. Confirm the webhook is **Subscribed** to `messages` under Meta →
WhatsApp → Configuration.
2. Confirm the phone number is listed under **Recipients** during testing
(test-number apps only deliver to whitelisted testers).
3. Check server logs — inbound webhooks hit
`POST /api/whatsapp/webhook`. A 200 with no message row means the
payload parsed successfully but didn't match any known contact's
config — double-check `phone_number_id`.
### `Token decryption failed`
`ENCRYPTION_KEY` changed since the token was saved. Reconnect the
WhatsApp account from **Settings → WhatsApp** to re-encrypt with the
current key.
## Automations
### Wait steps never resume
The cron drain is not running. See
[automations-and-cron.md](./automations-and-cron.md).
Quick sanity check from your machine:
```bash
curl -s -H "x-cron-secret: <secret>" https://crm.example.com/api/automations/cron
```
If that returns `{"processed":N}` with N growing when a wait is due, the
endpoint is fine and the problem is just the schedule.
### An automation fires twice for the same message
Most likely two WaCRM instances share one Supabase project and both
receive the same webhook. The webhook handler deduplicates by Meta's
`wamid`, but only within a single deploy — split-brain setups can double
up. Either consolidate to one deploy or route the webhook to exactly one.
## Deploy
### `502 Bad Gateway` or "Application not running" from Hostinger
- Open the Node.js app page in hPanel and confirm the status is **Started**.
- Check the app log viewer for a crash on boot — almost always a missing
env var. Re-save your env vars, re-run the build, and restart.
- Confirm the **Application startup command** is `npm start` (or
equivalent) and that a build has actually run (`.next/` exists in the
application root).
### Env var changes don't take effect in the browser
`NEXT_PUBLIC_*` values are baked into the client bundle at build time.
After changing any of them, re-run `npm run build` (hPanel's **Run NPM
Build** button works) and restart the app.
### Meta webhook suddenly stops after a domain change
Hostinger provisions a new SSL certificate when you attach a new domain
or subdomain. Until it is issued, the webhook URL serves plain HTTP and
Meta rejects it. Wait for AutoSSL to complete (minutes), then re-verify
the webhook in Meta.
## Still stuck?
Open an issue with:
- Environment (local / Hostinger Managed Node.js / other).
- The exact error from the app log viewer in hPanel or Next's dev output.
- What you were trying to do when it happened.
