/**
 * Side card settings section chrome (DSH-native tokens throughout):
 * - the feature inventories are responsive GRIDS of small toggle cards
 *   (auto-fill columns — several cards per row, wrapping);
 * - a card's on/off state IS its visual state: enabled = brand border +
 *   tinted fill + a check badge pinned to the far right of the top row,
 *   disabled = neutral hairline + dimmed text;
 * - features that declare related settings carry a gear corner button
 *   opening a native Modal whose rows are the DSH settings-row recipe
 *   (title/desc left + native accent checkbox, hairline separators);
 * - the width input stays a native settings row (a value, not a switch).
