/* Perfectly Good PC — design system v2 ("workshop paper")
   ----------------------------------------------------------
   Direction: the site is about beige-tower-era machines that still work,
   so the palette is grounded there — warm paper and greige surfaces, ink
   text, and LED semantics for status (power-light green = fine, HDD amber
   = caution, red = problem). Literata carries the reading voice; IBM Plex
   Mono carries anything that is a date, a label, or a fact-of-record.

   Fonts are self-hosted in ../fonts/ (latin subsets, ~156KB once, cached
   site-wide). Literata roman is a variable font covering 400–700.

   Theme model: bare :root defines the full light palette; the
   prefers-color-scheme block (guarded with :not([data-theme="light"]))
   and the [data-theme="dark"] block redefine tokens only. Components
   never reference a colour that isn't a token. */
