/* ─────────────────────────────────────────────
   Programme Explorer — page styles
   Fonts, colour tokens, header, footer and contact dialog come from
   /assets/css/main.css. Everything here is scoped to the explorer and
   built on the same tokens, so light and dark mode follow the site.
   Focus: readability of large tables on wide screens. Below 900px the
   interactive tables are replaced by a simplified mobile overview of the
   twelve capabilities and the SE contribution to each (see .pe-small-view),
   with an opt-in to the full explorer.
