   tpl-izgotovlenie.css — лендинг «Изготовление металлоконструкций на заказ» (ID 547), 16.10.2026.
   Идея «цех и ведомость»: тёмный завод, крупный узкий гротеск (Sofia Sans Condensed), моноширинные подписи
   (IBM Plex Mono), белый лист «черновик КП» как главный интерактив. Синий - только действия и наш вклад в цену.
   Палитра полосы «из чего цена» проверена валидатором dataviz (соседние ΔE ≥ 17,9, подписи рядом со значениями).
