/* alienmachine-ui — docs layout shell (theme-agnostic, structural).
 *
 * A modern three-zone docs page: a sticky left page-tree sidebar, a centered content column with a
 * comfortable reading measure + margins, and a sticky right "On this page" TOC. Colors come from the
 * active daisyUI theme's CSS variables (works under any reader-selected theme); only structure lives
 * here. Scoped entirely to `.amui-layout-docs`, so other layouts (article/landing/index) are untouched.
 *
 * Section order under .amui-page.amui-layout-docs is fixed by the CMS docs page-spec:
 *   row 1 = nav (top bar)        row 2 = theme-switcher (thin utility strip)
 *   then: doc-nav (col 1) · breadcrumb/content/search (col 2) · toc (col 3)
 * The sidebar/TOC span from row 3 down; the content column defines the row heights.
