   Iommix — shared site stylesheet
   Single source for the foundations repeated on every page: colour tokens,
   reset, base typography, headings, buttons, nav and footer. Page-specific
   rules stay in each page's own <style>. This file is linked AFTER that
   block, so it is the one that sets these shared pieces site-wide.
