/* Tobsy — the writing pages (2026-10-01). A READING surface on the site: paper by default, with a Dark switch that
   remembers the choice on the device. Both sets were settled on the blog's draft-3 review page (the human, over seven
   cuts of dark: white on near-black glowed, a grey ink went dull; what stayed is an ivory ink on a lifted violet-tinged
   dark, headings a step brighter, a hair of tracking and leading, a half step smaller). Georgia for the body (the italic
   the human chose), Gelasio embedded for phones that do not ship Georgia (Android); headings stay Newsreader; the chrome
   stays DM Sans / DM Mono. Loaded after styles.css; every rule is scoped to body.read, so no other page changes.
   THE SHAPE (the human, 2026-10-01): the reading column CENTRED on the page, the chapters in a sidebar to its left
   that follows the scroll, the post's title at the top of that sidebar, Dark and Share pinned above it; on a phone the
   sidebar is a contents card between the title and the text and the two buttons float in the corner, always in view. */
