📚 Description

A docs build logs 100 [Icon] failed to load icon warnings across a full prerender, for 14 distinct icons.

Two separate causes.

Collections that were never installed. The theme picker offers Lucide, Phosphor and Tabler and swaps appConfig.ui.icons wholesale, but only @iconify-json/lucide was a dependency. Only ph:star/ph:star-fill ever warned, because those are the two the InputRating page renders at build time, but every icon in both sets fell back to a runtime fetch the moment anyone switched. Adds @iconify-json/ph and @iconify-json/tabler; all 41 phosphor and 44 tabler names the picker references resolve against them.

Icons that no scan can find. ProseCodeIcon resolves through Nuxt UI's code icon map and falls back to i-vscode-icons-file-type-{extension}, and ProsePrompt hardcodes one logo per action. @nuxt/icon's clientBundle.scan walks nuxt.options._layers.map(layer => layer.cwd), so none of those names appear anywhere it looks, and they're left to runtime loading. That is currently broken during SSR (nuxt/icon#518), hence the warnings.

Listing them in clientBundle.icons is a workaround, not a fix, so it lives here rather than in the module and can be deleted in one line once nuxt/icon#527 lands. Doing it module-side would have meant bundling ~48 icons for every app using prose to work around an upstream bug, which is the wrong trade.

Also sorts src/theme/prose/code-icon.ts. Key order only, no entries added, removed or changed, and lookup is an exact-key match so it has no behavioural effect.

Verified on a full 2244-route prerender with the module-side version of this: 100 icon warnings → 0.

📝 Walkthrough

Walkthrough

The documentation package adds the @iconify-json/ph dependency. The Nuxt configuration adds explicit client-side bundling for Claude, Cursor, Windsurf, Bun, CSS, dotenv, Edge, Git, HTML, npm, PHP, pnpm, tsconfig, and Yarn icons. The prose code-icon mapping is reordered without changing its mapped keys or icon values.
