    This is a special variable (prefixed with \c $) that propagates
    automatically through the OpenSCAD child scope.  It scales
    line-level constructions such as line widths and arrowhead sizes.
 
    It is distinct from \ref draft_sheet_scale, which is a plain
    variable that scales sheet-level geometry but does not propagate
    through children.  In typical use both are set to the same value:
 
    \code{.C}
    draft_sheet_scale = 2;       // scale sheet frame and zones
 
    draft_move ( [ ... ] )
    {
      $draft_scale = draft_sheet_scale;   // propagate to children
      // ...
    }
    \endcode

$draft_scale = 1;
 
//! <integer> Sheet construction drafting scale multiplier.
/***************************************************************************//**
  \details
 
    This is a plain (non-special) variable set once at design time.
    It scales all sheet-level constructions — frame dimensions, zone
    widths, title-block sizes, and table cell sizes — by the given
    factor.  It does \b not propagate automatically through the
    OpenSCAD child scope.
 
    Contrast with \c $draft_scale, which is a special variable that
    \b does propagate through children.  When constructing elements
    that must track sheet scale dynamically (e.g., objects placed via
    \ref draft_move), set \c $draft_scale explicitly inside the child
    block:
 
    \code{.C}
    draft_move ( [ ... ] )
    {
      $draft_scale = draft_sheet_scale;
      // child objects here inherit $draft_scale
    }
    \endcode
 
    Both variables default to \c 1 (no scaling).

/***************************************************************************//**
  \details
 
    Controls which layers are rendered.  Only modules whose \c layers
    parameter contains at least one name that also appears in this list
    will produce geometry.
 
    The string \b "all" is a wildcard that matches every layer list,
    so setting this variable to \c ["all"] renders everything regardless
    of individual layer assignments.
 
    Layer names are arbitrary strings.  The library assigns the
    following default names by module category:
 
     layer name     | category
    :---------------|:---------------------------
     \c "default"   | general-purpose geometry (\ref draft_in_layers)
     \c "sheet"     | sheet frame, zones, rulers, axes
     \c "table"     | tables (\ref draft_table, \ref draft_ztable)
     \c "note"      | text notes (\ref draft_note)
     \c "titleblock"| title block (\ref draft_title_block)
     \c "dim"       | all dimension modules
 
    Custom layer names can be used freely — pass any string as the
    \c layers argument to any module, then include that same string
    here to enable it.
 
    \b Example — render geometry and dimensions only:
 
    \code{.C}
    draft_layers_show = ["default", "dim"];
    \endcode
 
    \b Example — render everything:
 
    \code{.C}
    draft_layers_show = ["all"];
    \endcode
 
    \b Example — render a custom layer alongside the sheet:
 
    \code{.C}
    draft_layers_show = ["sheet", "mypart"];
 
    draft_in_layers(["mypart"])
      import("mypart.dxf");

    A title block is constructed using \ref draft_ztable "zoned tables".

    overrides to this style map. The map keys and structure depends on
