/* ============================================================================
   TestTech LABWork — application chrome.

   Ported from the approved UI design (Claude Design canvas "LABWork v3").
   Colours are sampled from the Test Tech logo (accent #2f87c9 is also the
   natural water-lab brand blue); the typeface is Prompt, a Thai/Latin sans,
   because the whole interface is Thai-primary.

   The canvas also linked a "Broadsheet" design system, but that system is a
   newsprint/serif kit whose component classes (.card, .table, .btn, .input)
   collide with the ones below and whose JS bundle is only CMYK print-plate
   SVG filters that this interface never uses. Only the four reset primitives
   the layout genuinely depends on were carried over — see "inherited reset".
