Tailwind CSS v4: стили Tailwind.config.js не применяются после обновления с версии 3 ⇐ CSS

[Anonymous]

Недавно я обновил свой проект с Tailwind CSS v3 до v4 и использую Next.js 16.0.8 с Tailwindcss ^4.0.0. В версии 3 я в значительной степени полагался на Tailwind.config.js для настройки цветов, размеров шрифта, интервалов и расширений темы. После обновления эти стили больше не применяются, поскольку в Tailwind v4 удален традиционный файл конфигурации. Как правильно перенести или повторно применить эти значения конфигурации v3 в Tailwind v4?
это мой файл main.css в версии v4:
/*! tailwindcss-build-file - DO NOT REMOVE THIS COMMENT. It is used in /scripts/run-after-build.js */
/**
* MAIN CSS ENTRY POINT - Tailwind CSS v4
*
* This file is the single source of truth for all styles.
* Import order matters!
*/
