   CODE SAVANT — THE STANDARD STYLESHEET
   The one place the design system is defined. Every frontend loads this file first, then
   adds only what is specific to itself.

     site/     marketing pages   <link rel="stylesheet" href="codesavant.css">  (before style.css)
     portal/   tenant portal     <link rel="stylesheet" href="codesavant.css">  (before style.css)
     web/      operator console  @import in web/src/style.css

   `shared/codesavant.css` is the only real copy. `portal/codesavant.css` and
   `site/codesavant.css` are symlinks to it, and the deploy scripts rsync with -L so each
   docroot gets a materialized file — there is no second copy to drift.

   RULES
   1. Design tokens (the `:root` block) live HERE and nowhere else. An app that redefines
      one is a bug: the values below drifted into three copies once already, and the
      operator console spent months on a `--muted` that failed WCAG AA because nothing
      tied it back to the corrected value.
   2. Anything a second page could reasonably want — a button, a card, a form control —
      belongs here. App files are for layouts and one-off components.
   3. Extend with a modifier class, don't fork the base: `.btn.small`, not `.my-btn`.
   4. Changing a token or a component here changes all three frontends. Their Playwright
      suites (`npm run test:e2e:all`) are the check that it was intended.

   TENANTS OVERRIDE SOME OF THIS AT RUNTIME — DO NOT BREAK IT
   White-label branding repaints `--orange` (accent) and `--ink` (primary) per tenant, set
   as INLINE properties on documentElement (`applyBranding` in portal/app.js, `paintTheme`
   in site/tenant.js). Inline wins over every stylesheet, so this file cannot clobber a
   tenant's brand — but two rules follow from it:
     • Anything that should follow the brand must reference var(--orange) / var(--ink).
       A literal hex freezes it at Code Savant orange on a tenant who chose blue. The few
       literals below are neutrals (greys, the chevron, the focus halo) that stay put on
       purpose, or spots where a var cannot go — inside a data: URI or an rgba().
     • Do not add `!important` to a branded property. That beats the inline override and
       silently un-brands every white-label tenant.
   The customer-facing tenant site (site/tenant.html + tenant.css) is deliberately NOT on
   this stylesheet: its tokens are the tenant's to theme, not the house system's.

   The look is a dispatch office: paper gray, gunmetal, safety orange. Barlow Condensed
   for display, Archivo for text, IBM Plex Mono for data.
