/* MOMENTUS · the shared top bar (B148, B149): one glass bar on every momentus.gg page.
   Markup and behaviour: /shared/topbar.js. Geometry is the archive's Figma bar (x 31, y 32, 1858 x 68 on
   the 1920 frame), scaled to the window.
   B149: plain glass. backdrop-filter blurs exactly what is under each point of the bar over a very light,
   neutral, low-alpha fill: over a light list it reads light, over a dark showcase it reads dark, with no
   sampled tint (nothing to flicker on scroll). Text and mark switch between white and near-black per word,
   from what sits directly under each one, only after scrolling stops. */
