turn the terminal/Gruvbox theme into the skeuo console

- rename the theme everywhere: id terminal -> skeuo, desktop sim skeuo -> desktop,
  skeleton terminal shell -> SkeuoLayout, page.css -> shared.css (shared components),
  old skeuo.css -> desktop.css, storage key theme -> dmx-theme (with migration)
- rebuild the theme as a walnut-and-aluminium home-lab console: brass plates, patch bay,
  analogue gym gauges, clipboard, stitched leather logbook, service rack with pilot lamps,
  framed print, chart recorder, cartridge, software box, pegboard tags, card-index drawer
- all materials are CSS + inline-SVG noise (no texture images); Barlow Semi Condensed +
  Courier Prime via next/font with fallbacks
- desktop mode is now phone-only (<=768px): switch hidden above that, stored desktop
  preference overridden, sim never mounted on wide viewports
- drop the ASCII train background and its gruvbox.webp asset

-  On phones it becomes an **iOS-style home screen** with a widget grid, dock, drag-to-reorder

-  train background, a clickable easter-egg logo, and a working in-browser terminal (Alacritty)
-  with commands like `help`, `ls`, `cat`, `neofetch`, `emerge`, `ssh` and more.

+  modules with live pilot lamps, a framed screenshot, a chart recorder, a game cartridge, a

+  noise only: the theme ships **no images of its own**. One light source (top-left), layered

+- **CSS-only materials** — wood, brushed aluminium, brass, leather, black bakelite, paper, glass
