-  /* responsive base size: scales with viewport (2.1lvmin) on top of a
-     fixed floor (3pt) so it keeps growing on large/wide screens
-     instead of capping at a fixed px value like the old 17px did;
-     max(12px, ...) keeps it from shrinking below legible on tiny
-     viewports. lvmin (large-viewport min), not plain vmin or svmin -
-     plain vh-based units recalculate as mobile Safari's address bar
-     hides/shows on scroll, which would reflow every text size on the
-     page mid-scroll. svmin would be stable too, but pinned to the
-     *smallest* (toolbar-visible) state - wrong end for a page whose
-     toolbar collapses the moment you scroll: same mismatch as
-     .hero-yes below, just for font-size instead of height. lvmin
-     matches the settled (toolbar-collapsed) state scrolling actually
-     lands on.
-     Plain-px fallback declared first: an engine that doesn't
-     understand lvmin/calc() here treats the whole line as invalid and
-     ignores it, leaving this in effect instead of falling through to
-     the UA default. */
