- sidebar and TOC typography/colors moved from 08-layout.css to 03-components.css
- nav[data-nav="sidebar"] and aside[data-toc] layout-only rules remain in 08-layout.css
- <small> section labels replaced with <h3> in sidebar and TOC (semantic + accessible)
- dead selectors removed: nav[data-nav="sidebar"] nav a → nav[data-nav="sidebar"] a,
nav[data-nav="toc"] (Hugo never outputs data-nav="toc")
- webkit scrollbar pseudo-elements removed (scrollbar-width/color sufficient)
- sidebar/TOC sticky top values split: sidebar top space-4, TOC top space-8 + padding-top
- max-height magic number (--size-px-10) replaced with token expression
- layer convention established: 03=component identity, 04=modifiers, 08=placement only
