// Remix Icon (ri) subset that backs apps/kimi-web's icon registry.
//
// Single source of truth for "which existing icon name maps to which Remix
// icon" is the NAME_TO_REMIX map below. The SVG bytes are pulled straight from
// @iconify-json/ri at generation time, so the registry stays library-sourced
// (no hand-copied SVG) yet fully offline and tree-shaken (only the icons we
// list here end up in the bundle).
//
// Run after changing the map:  pnpm gen:icons
