/* MakerKiln — "Machined Instrument" system (v2).
   v1 "Shop Drawing" REJECTED (flat thin-border wireframe = cheap; tool buried
   under a hero). v2 law: TOOL FIRST — slim header, one compact title strip,
   then the bench fills the first screen. Craft = layered depth: gradient
   panels on a darker ground, hairline borders + real shadows + inset wells,
   a DRO-style readout screen with glowing ice-blue digits. Palette = John's
   spec: dark grey, neutral, dark ice-blue accent; kiln ember lives ONLY in
   the logo mark. Dark is the house default; light is the toggle.
   Class hooks kept for kiln tooling (.forge/.rail/.ctl/.seg/.chips/.bar/
   button.act/.ghost/.local-note/section.prose/.tool-index/header/footer/
   .toggle). Fonts: Big Shoulders · Archivo · Chivo Mono. */
