-## 19. Inline SVG Icons — LOW PRIORITY
+## 19. Inline SVG Icons — MOSTLY DONE
 **Penguin UI: none (Penguin uses Heroicons-equivalent inline SVGs)**
 
-> **Priority: LOW** | ~50 lines,8 distinct icons.
-> Penguin doesn't provide an icon library. Icons are already inlined where used.
-> Possible follow-up: extract into a `ui::icon(name)` macro for dedup, but
-> this is purely cosmetic — no functional gain.
+> **Priority: LOW.** Penguin ships no icon library, so this is dedup, not a port.
+> The repeated hamburger / close / cart SVGs are now centralized in the
+> `ui::icon(name, size, extra, attrs)` macro (`macros/ui.html`); call sites use
+> `{{ ui::icon(name="cart") }}` etc. The chevron dropdown arrows stay inline by
+> design — they carry nested-quote Alpine `:class` / `x-bind:class` bindings,
+> which Tera macro args can't pass cleanly (see the attrs note atop `ui.html`).
