/* ============================================================
   CONF — Settings, Upload, Share & API Key Management
   WhoDASH / Belmont Labs — BL-002
   ============================================================
   Sources consolidated from:
     sections_conf.php lines 482–1443 — entire inline <style>
     block. Nothing for this section existed in style.css;
     all styles were self-contained in the PHP file.

   Sections covered:
     - Upload & management cards (shared card shell)
     - File input wrapper + label + upload button
     - Management grid + items + danger zone variant
     - Button palette: danger, secondary, cancel, save,
       confirm-delete, final-delete, confirm-share, unshare,
       copy, upload, primary
     - Modal system: overlay, content, header, body, footer,
       slide-in animation
     - Delete flow: warning-box, confirmation-input,
       final-warning
     - Upload progress modal: progress bar + shimmer,
       progress stats / text / message
     - Share modal: share-info-box, share-note, share-options,
       checkbox-group/label, share-url-box, url-display-group,
       copy-btn, copy-success
     - API Keys section: api-keys-card/info/list, loading
       spinner, no-keys-message, api-key-item/header/details,
       key-status badges (active/inactive/expired),
       key-btn palette (activate/revoke/delete),
       modal-large, success-box, api-key-display,
       key-copy-group, key-input, next-steps-box,
       key-name-display, form-group/input/select, label-hint

   PENDING ACTION: Remove the inline <style> block from
   sections_conf.php (lines 482–1443) once this file is linked.

   NOTE: .copy-btn is defined twice in the source (share
   modal ~1061 and API key display ~1346) with identical
   rules — merged to a single definition here.
   .copy-success similarly appears twice (~1078 / ~1363) with
   slightly different margin values; the API key version
   (margin-top: 8px, font-weight: 600) is used as canonical.
