Shopify nav icon cleaner

Shopify's sidebar icon under Apps must be a single-colour, transparent-background SVG that renders cleanly at 16×16. Drop your mark in — we strip backgrounds, gradients, filters, and stray width / height attributes, flatten every fill and stroke to currentColor so Shopify can recolour for active and inactive states, and optionally tighten the viewBox so the mark sits centred at small sizes. Nothing leaves your browser.
