   MAP UI LAYOUT PRINCIPLES — foundational rules
   ============================================================

   The map has two classes of floating UI; they coexist by
   following a few fixed rules. If you're adding a new panel,
   button, or viewer that floats over the map, pick the class
   it belongs to and follow the rules for that class.

   1. CONTEXT surfaces — persistent, represent user state.
          * #details-sidebar (selection panel, right edge)
          * #mapillary-container.floating-viewer (Street View)
      These own their space. Users open them deliberately and
      expect them to stay put. They do NOT shift or collapse
      when transient UI appears.

   2. CONTROL surfaces — transient, user opens → picks → closes.
          * #filter-panel
          * #layers-panel
          * #boundaries-popover
      These anchor to the top-right. They:
        (a) auto-close each other (one at a time), via the
            'floating-panel-open' CustomEvent.
        (b) dismiss on outside click and Escape.
        (c) never occlude a context surface — they shift left
            by --sidebar-width when body.sidebar-visible, so
            the selection panel is always visible beneath them.

   3. CONTEXT surfaces yield to CONTROL surfaces on the same
      edge. The Street View PiP sits bottom-right; if a control
      panel opens, SV shifts further left by --control-panel-
      offset so the user's current pick remains visible. When
      the control panel closes, SV slides back.

   The CSS variables that implement these rules:
        --sidebar-width          width of the selection sidebar
        --control-panel-offset   width + gap of the currently-
                                 open control panel (0px when
                                 no panel is open)

   Transitions on 'right' are deliberate: a sudden snap looks
   like a bug, a smooth slide reads as intentional reflow.
   ============================================================ */

/* ============================================================
   DESIGN TOKENS — foundational primitives
   ============================================================
   Rules:
   * Components reference tokens, not raw values. If you're
     about to type '4px' or '#fff' in a panel style, look for
     a token first. Adding a new one is cheap; drifting is
     expensive.
   * Tokens are grouped by axis: spacing, radius, shadow,
     motion, z-index, color. Adding a new axis = new group.
   * Dark-mode tokens override semantic colors under
     body.theme-dark. Never theme individual components
     directly — always theme via token.
   * Layout primitives (--sidebar-width, --control-panel-
     offset) are set dynamically by JS; they live here for
     documentation even though their values change at runtime.
   ============================================================ */
body {
    /* Layout primitives — set/overridden at runtime by JS.
       Keep in sync with the literal 380px in index.html
       #details-sidebar { width } — the variable here drives
       every offset that anchors against the sidebar's left
       edge (icon rail, top-right popovers, floating header). */
