  /* v1.36.0 (N66 / WD-693) — Neil, iPhone: "the view is pretty narrow". MEASURED at 390 wide:
     the accordion's content gutter (26px each side) plus our 12px left a 278px column, and a
     fixed 400px box held a 6,000px document — a quarter-screen scroller. Now the wrapper
     reclaims the content gutter (the panel is overflow:hidden at the accordion's outer gutter,
     so that is the honest ceiling: 354px), the doc keeps a 16px gutter (322px of text), and
     the canvas is 75% of the VISIBLE viewport — dvh, with vh as the fallback for browsers
     without it (root CLAUDE.md reachability rule). Fullscreen mode (.slib-canvas--fullscreen,
     two classes) still outranks this height.
     --slib-gutter is set by slib-reader.js from the content's COMPUTED padding-left. The
     component's own token is the shorthand "20px 26px 26px" (unusable in calc) and no
     --space-* token equals 26px; the fallback is the value measured live on staging + prod. */
