Initial import: Majd Trading website

Next.js 15 site for گروه بازرگانی بین المللی آریو مجد آسیا, rebuilt from
majdtrading.com. Persian, English and Arabic; RTL and LTR.

- Pages: home, about, contact, six product categories, blog index and detail
- i18n: prose in per-locale JSON, structure in TypeScript, drift checked by
  `npm run i18n:check`. Blog stays single-language by design
- Meshkee backend: blog content, tenant resolution, session via the customer
  portal, and /meshkee/sitemap-config.json
- Live market data from livedata.ir, cached server-side once a minute
- Self-hosted fonts: IRANYekan (fa), IBM Plex Sans Arabic (ar), Space Grotesk
  and BBH Bartle (Latin)

+ *
+ * Ids are the anchor because the page is ad-heavy and its layout shifts, but an
+ * id has a fixed meaning. `fa` is the label as published upstream — used to
+ * identify the row when choosing, and as a fallback if no translation exists yet.
+ *
+ * Nothing here is displayed on its own. Pick what to show in `displayed.ts`.
