▌
Icons · laguagu
Find, fetch, and install the right icon or logo from the right source — brand marks, country flags, file-type icons (PDF, DOCX, ZIP), and UI glyphs — and keep them visually consistent with the app. Use when the project's icon library has no match, when svgl comes up empty, or when the user asks for a flag, a file-type badge, a brand logo, or just "an icon for X". Covers the Iconify search API (200k+ icons across flags, file types, logos and UI sets), the svgl shadcn registry for full-colour brand logos, family and stroke-weight matching so a borrowed icon does not look pasted in, and how to reach svgrepo through browser automation when curl and WebFetch are blocked. Triggers on "lisää ikoni", "maan lippu", "flag icon", "PDF icon", "file type icon", "brand logo", "sign in with Google/GitHub", "language switcher", "svgl", "iconify", "find an icon". For overall visual direction rather than sourcing one specific mark, use ui-signature; for installing shadcn components generally, use shadcn.
