/* Safety net so no page can ever produce a horizontal scrollbar on any device. Uses
   overflow-x: clip, NOT hidden — "hidden" on one axis forces the browser to compute the
   other axis as auto (a CSS spec quirk), silently turning html/body into a scroll
   container, which breaks position:sticky (header, admin sidebar, etc. stick to that
   phantom container instead of the real viewport scroll). clip has no such side effect,
   and still doesn't affect intentional inner scrollers (.table-responsive, etc.), which
   scroll within their own container regardless. */
html { overflow-x: clip; width: 100%; }
/* Bootstrap's reboot default line-height (1.5) reads a bit cramped for real paragraph
   content — a slightly looser baseline makes body copy across the whole site easier to
   read without needing every individual content block to set its own line-height.
   font-size is explicit px (17px, +1px over the browser/Bootstrap 16px default) rather
   than rem, deliberately — a change to :root/html's rem basis would also rescale every
   rem-based size sitewide, including the blog module's own explicit rem sizes
   (.blog-article-content etc.), which must stay untouched. A plain body font-size only
   changes text that inherits it directly (most descriptive/body copy across the site);
   anything already given its own explicit font-size (blog, the typing engine, Bootstrap
   components) is unaffected either way. */
