/* needleBaseStyles.css — Cratoora Needle
   Flat shell architecture — no stereo-shell wrapper.

   SIDEBAR EXPAND / OVERLAY ARCHITECTURE
   ──────────────────────────────────────
   The sidebar expands ON TOP of the main content (Spotify-style overlay).
   The content panel left offset NEVER changes. Only the sidebar width grows.

   Default:   cratoora-needle-sidebar  width: --needle-sidebar-w (320px)
              #needleContent           left: var(--needle-sidebar-w) = 320px

   Expanded:  cratoora-needle-sidebar  width: --needle-sidebar-expanded (560px)
                                       z-index: 150 (above content)
              #needleContent           left: 320px  ← UNCHANGED
              #sidebarExpandBackdrop   visible over content area

   Expand button is AUTH-GATED — only shown when cr_auth_token exists.
   Guests get inner scroll only (Spotify pattern for logged-out state).

   MOBILE LAYOUT STRATEGY (dvh-based)
   ────────────────────────────────────
   body has NO padding-top. Top clearance handled by margin-top on
   #needleContent. dvh units absorb Android Chrome URL bar animation.
