- Drop the fixed max-width on .header-container so the header spans the
viewport while the card grid keeps its own content width
- Keep header icon click targets at 32px at all breakpoints and add
role/tabindex/aria-label plus Enter/Space activation
- Relocate the Doctor trigger from the page toolbar to the header icon
group (also available on the statistics page and in the hamburger
menu), removing the now-unused .doctor-trigger styles
