 * Dimensional Drawing Stage Correction
 * ---------------------------------------------------------
 * Scope:
 * - Fix V11.6.3 over-scale clipping on Dimensional Drawing.
 * - Let transparent SVG sit on website-controlled engineering paper.
 * - Keep Product Structure View unchanged because current effect is approved.
 * Principle:
 * - Do not use aggressive scale() that crops dimension labels.
 * - Background visibility requires SVG file itself to be transparent.
