Add global :focus-visible outline style and migrate form components
from :focus box-shadow to :focus-visible outline. Refactor accordion
chevron from CSS ::after pseudo-element to explicit span element.
Children were appended to the outer <details> element instead of inside
the .accordion-content div, causing text to render outside the accordion
box. Also adds .accordion-group wrapper to eliminate parent gap between
stacked items, and styles content with smaller font and muted color.
Refactor card to use flex column with gap-based spacing instead of
per-section padding, tightening the space between header, body, and
footer from size-6 to size-3. Add .card-footer .btn override to
render buttons at font-base size.
