/* documents.css
 *
 * Device Documents styles (the per-device Documents modal: list, upload,
 * preview, download, version history, deletion), extracted from
 * styles.css as part of Stage 2 of the frontend modularization plan
 * (docs/planning/frontend-modularization-and-csp-hardening-plan.md).
 *
 * Scope matches js/modules/documents.js exactly. Does NOT include the
 * Admin tab's Document Storage quota settings panel (a Stage 5 concern,
 * and confirmed to use no documents-*/doc-* classes of its own), or the
 * plain-text preview modal's content styling (.logcat-view-meta /
 * .logcat-view-content), which is shared with the Service tab's logcat
 * viewer and stays in styles.css until that's migrated.
 *
 * Load order: linked in index.html after core.css and automation.css,
 * before styles.css.
