 * ---------------------------------------------------------------------------------------------
 * THE OVERFLOW RULES. Read these before adding anything.
 * ---------------------------------------------------------------------------------------------
 *
 * Three separate bugs produced "white bars at the edges" and a page that scrolled sideways. All
 * three were something creating scrollable area beyond what any element paints:
 *
 *   1. `.skip { left: -9999px }`. The classic off-screen trick for a skip link EXTENDS THE
 *      SCROLLABLE REGION nine thousand pixels to the left. The page then scrolls sideways into
 *      empty, unpainted canvas. It is visually hidden with `clip-path` now, which takes the
 *      element out of the paint but leaves it exactly where it is in layout, so it adds nothing
 *      to scroll.
 *   2. A background on an element that also had `max-width` and `margin: auto`. A constrained
 *      element cannot paint to the viewport edge. Sections paint and are always full width; the
 *      inner `.wrap` measures and never paints. Never both on one element.
 *   3. Relying on background propagation from body to the page canvas. html, body and every
 *      structural block now carry the colour explicitly.
 *
 * `overflow-x: hidden` on BOTH html and body is the backstop, not the fix. If you ever see a
 * horizontal scrollbar again, something is genuinely too wide; find it rather than adding more
 * hiding.
