# AGENTS.md — polyblender.ru/en/

English version of a static marketing site for a manufacturer of industrial casting equipment
(SARMATECH LLC, Russia). No API, cart or online payment.

## Structure
Four product pages and two catalogue pages, each a separate URL with its own canonical and a
single `Product` entity in JSON-LD:

- `/en/` — polyester line (UPR)
- `/en/pmma/` — acrylic line (PMMA)
- `/en/pu/` — polyurethane line (PUR)
- `/en/ep/` — epoxy line (EP)
- `/en/catalog/pe/`, `/en/catalog/pu/` — full catalogues

Every page is fully present in the server-rendered HTML. JavaScript handles the mobile menu,
the sticky header and reveal animations only; the data is readable without executing it.

## Language pairing
Each English page declares `hreflang` alternates for `en`, `ru` and `x-default`; the Russian
pages declare the same set in reverse. Russian is `x-default`, since the site is a Russian
manufacturer's and the Russian version is the original. The English version covers the same
four binder systems — it is a parallel version, not a subset.

## Machine-readable sources
- `/en/llms.txt` — summary of all four lines, parameters, products and references
- `/en/pe.md`, `/en/pmma.md`, `/en/pu.md`, `/en/ep.md` — markdown mirrors of the pages
- `/en/catalog/polyblender-pe.md`, `/en/catalog/polyblender-pu.md` — machine-readable catalogues
- All declared through `<link rel="alternate" type="text/markdown">`
- JSON-LD in the `<head>` of each page: `Organization`, `Product`, `Service`, `FAQPage`,
  `BreadcrumbList`

## Prices
No price list. Every line is engineered and built to the customer's technical specification,
and the price is determined after the specification is agreed. `Offer` is therefore
deliberately absent from the markup; the `Service` entity (`#service`) describes this supply
model.

## Available actions
Enquiry: `POST /send.php` with `name` (required), `contact` (required), `message`, `subject`.
The `_gotcha` field is a honeypot and must stay empty. On success the server responds with a
303 redirect to `/spasibo/` (the confirmation page is in Russian).

## Reference installations
Named on the Russian version of the site; anonymised here at the customers' discretion.

## Crawling
No restrictions: `robots.txt` explicitly allows GPTBot, ClaudeBot, PerplexityBot, CCBot,
Google-Extended, Applebot-Extended and other known AI crawlers.

## Printed catalogues
The PDF catalogues are the Russian printed editions, 13 pages each, with a text layer. Their
English equivalents are the HTML and markdown catalogue pages listed above.
