Theme Name: InsightDesk
Theme URI: https://insightdesk.example
Author: InsightDesk
Description: A clean, minimal editorial WordPress theme closely modeled on the classic Business Insider layout — hamburger menu + centered wordmark logo + Login/Subscribe header, bold black category title bars, and a symmetric 3-column featured story row (small / big / small). Header navigation is an off-canvas drawer, editable under Appearance → Menus. Homepage/category pages show the site's latest posts in a simple row layout with a sidebar of ad spaces. Single articles show classic blue in-content hyperlinks, end-of-article tags, and an unlimited "keep loading" related-articles section.
Version: 1.0
Requires at least: 5.9
Requires PHP: 7.4
