 - **`docs/DocsPageHeaderLinks.vue`** — gave the "Copy page" button group the same translucent-dark card styling used everywhere else on the site. Purely cosmetic: the stock Nuxt UI button styling didn't match the rest of the page chrome and stood out as an unstyled default.
 - **`prose/ProseNote.vue`, `ProseTip.vue`, `ProseWarning.vue`, `ProseCaution.vue`** (new files, no stock equivalent to override against — these are thin wrappers around Nuxt UI's own `Callout.vue`). Nuxt UI's admonition icon is normally set once, globally, per icon slot — there's no built-in way to omit it on just one specific admonition without changing it for every admonition of that type site-wide. These wrappers read an optional `icon` prop so a single instance can hide its icon (`::note{icon=""}`) when the emoji or leading text already conveys the same meaning, while every other `::note` on the site keeps its default icon.
 - **`content/Ellipsis.vue`** (new; no Docus or Nuxt UI equivalent exists at all). The old site had a decorative blurred gradient glow behind section headers, and reproducing the content 1:1 meant this cosmetic effect needed *some* markdown-usable component to exist, since neither Docus nor Nuxt UI ships anything similar. Registered as the inline MDC component `:ellipsis{left= width= top= blur= zIndex=}`, used across content wherever the old site had that effect.
+- **`content/FileTree.vue` + `content/FileTreeNode.vue`** (new; no Docus or Nuxt UI equivalent exists at all). Every install guide used to show its folder layout as a plain ASCII-art code fence (`└──`/`├──`); this renders the same information as an actual tree with per-entry folder/file icons instead, reusing the exact filename/extension icon lookup `CodeIcon.vue` already does for labeled code fences, so a `.env` or `.conf` gets the same icon here as in a fence header. Registered as the container component `::file-tree`, fed through a YAML props block (`remark-mdc`'s `---\n...\n---` syntax) rather than a nested markdown list, since the data (name, whether it's a folder, its children) doesn't map cleanly onto list semantics otherwise. A trailing `/` on a plain string marks an otherwise-childless folder (a mapping key is unambiguously a folder already); a trailing `" # comment"` on either form renders as a dimmed, italic aside, matching a real code comment without being one (an actual unquoted YAML `#` would just be stripped by the parser before the component ever saw it). The header doubles as a collapse toggle (`collapsed` prop sets the initial state only), and clicking any row copies that entry's full path to the clipboard.
