 * The rail (aside.note-toc) is filled by buildToc() in collection.js from the
 * note's own h2/h3 headings, and left empty (:empty hides it) when a note has
 * too few sections to be worth one. The note body stays at the normal .wide
 * width so it lines up with the note header above it.
 *
 * Mobile-first: the index is a bordered, self-scrolling box above the note.
 * On wide screens it floats into the left gutter beside the centered body and
 * sticks as you scroll, highlighting the section you're in — same pattern as
 * /notes/networking/. Below that width there's no gutter, so it stays a block. */
