Overview

Catalogue of WarmlyYours heating-system product families, each
identified by a short code (TZ, EV2, SMC, …) and a customer-
facing name ('TempZone Flex Roll', 'Environ Easy Mat', …). Also
carries the marketing callouts used on the public landing pages and
is comparable so collections of systems sort consistently.
