/* ───────────────────────────────────────────────────────────────────────────
   stockmind.io — shared styles

   Navigation, logo, figures and print rules, in one place. These used to be
   duplicated across eight pages and drifted: one page styled a container class
   that had been renamed, another had no unconditional layout at all, and a
   later-appended rule silently overrode a media query so the mobile menu
   stopped collapsing.

   Loaded AFTER each page's inline <style>, so these rules win. Page-specific
   styling stays inline.
