   Design tokens are vendored from "MyBizBoss — Brand Style Guide v1.md" (see the
   VENDORED BRAND TOKENS block below). Rules encoded here as constraints:

     - Orange (#E6751B) is an ACCENT ONLY: thin borders, small status dots,
       toggles/checkboxes, the active-nav underline, and the literal "+" in
       product names. It is NEVER a fill under text and never a glyph fill.
     - Orange and Blue are NEVER placed directly adjacent to one another.
     - Product line names render Montserrat/Navy; only the "+" is Orange.

   linking to a shared hosted file — the product app is payroll-critical and
   must not gain a runtime styling dependency on this site's host, or vice
   versa. When Arch pushes a token update, replace this whole block verbatim.
   Site-specific colours belong in the "Site-local" block underneath, so a
   re-vendor never clobbers them.

/* ---------- Topbar ----------
   White bar carrying the FULL-COLOUR lockup, so the brand's orange appears in
   the mark. Decided with Bob 2026-09-10.

   Why this rather than recolouring the logo for a navy bar: the style guide
   forbids creating logo variants outside the four approved ones, but lists the
   navy topbar under "Component patterns", which it describes as "the reference
   implementation, not yet a formally itemized component library". Changing the
   bar bends a provisional convention; recolouring the mark would break a hard
   rule. The orange active-nav underline is unchanged.

   The hairline border and faint shadow are load-bearing: without them a white
   sticky bar over a white section has no edge. */
