   3. FOCUS

   Restores the focus ring that app.css removed application-wide.

   Uses outline rather than box-shadow deliberately. Blazorise emits
   .form-control:focus rules from a <style> element inside <body>, which
   comes after this file in document order and wins any specificity tie, so a
   box-shadow ring would be overridden. Neither Bootstrap nor Blazorise ever
   sets outline to a colour, and the leading `html` lifts this to (0,2,1),
   beating Bootstrap's .btn:focus-visible{outline:0} at (0,2,0). No
   !important needed.

   Do not add border-radius here - outline already follows the element's own
   radius, and setting it would change the element's shape on focus.

/* FocusOnNavigate in Routes.razor focuses the h1 on every navigation.
   Unconditional on purpose. The obvious :not(:focus-visible) form does NOT
   work: Chromium reports :focus-visible = true for a programmatic .focus() on
   a tabindex="-1" element, so the guarded rule never matches and the browser's
   default outline draws a box around the page title on every navigation.
   Verified in-browser, not assumed.

   Nothing is lost by suppressing it - a heading is not interactive, and this
   focus exists only to move the screen-reader cursor to the top of the new
   page. Interactive elements keep their ring from the rule above. */

   4. SCROLLBARS
   Moved from app.css and pointed at tokens.

   The element selectors here used to be a workaround: MainLayout.razor carried
   an inline <style> setting *::-webkit-scrollbar-thumb from inside <body>,
   which beat any universal rule in this file, so these were written narrow
   enough to win on html/body/.content/.modal-body and the rest of the app was
   left to MainLayout. That block is gone, and the webkit rules below are
   universal again - which is what actually shipped, since MainLayout is
   rendered on every authenticated page.

   The standard properties stay on the four scroll containers. scrollbar-color
   inherits, so setting it on every element is redundant and costs a style
   recalculation on every node.
