/* NVQ Portal — dark dashboard theme, amber accent, top header + left
   sidebar. Plain hand-written CSS, no build step. Palette/type/shape
   deliberately matched to the Burraq ISO Portal (BIPM) design language:
   slate-950/900/800 surfaces, amber-500 accent, Plus Jakarta Sans,
   generous rounded corners. One `@import` for the webfont is the only
   external request this file makes.

   Sizing: BIPM keeps its whole UI compact by setting the root font-size
   below the 16px browser default (its rem-based Tailwind spacing/type
   inherits that automatically) plus tight, mostly-px component paddings.
   Mirrored here: html below sets the same 15px/13px root, and every
   fixed-px dimension (avatar/icon circles, header height, card/button/
   input padding) is sized to match rather than left at the original,
   more spacious pass. */
