# CSS / HTML cleanup — loose ends

Found during sidebar/TOC refactor session (2026-04-11).

## Redundant resets

- `nav[data-nav="sidebar"] ul li { margin: 0; padding: 0 }` — browser default for `<li>` already has no margin/padding. No-op, remove.
- `aside[data-toc] nav ul li { margin: 0; padding: 0 }` — same.

## Semantic HTML

- `<small>← Previous</small>` and `<small>Next →</small>` in prev/next footer (`docs/single.html`, `vault/single.html`) — `<small>` is fine print, not a directional label. Replace with something appropriate.
- `role="main"` on `<article>` in `docs/single.html` — redundant and misleading. `<article>` does not map to the `main` landmark; `<main>` does. Remove the attribute.

## i18n

- `"On this page"` is hardcoded in `docs/single.html` and `vault/single.html`. Move to Hugo i18n strings or a site param before adding any second language.
