- Add .table-toolbar to mobile hide list (was rendering duplicate
'TRACKED PLAYERS' header above the mobile section-head)
- Change .m-card__body grid to minmax(0, 1fr) auto so the stats
column can shrink below content size
- Add min-width: 0 to .m-card__stats for proper grid shrinking
- Remove grid-row: span 2 from .m-card__sparkline (single-row grid)
- Remove overflow: visible from .m-chart-spark so the end-dot stays
within the SVG viewport
- Hide desktop .card-section on mobile, add .m-search-input with same
HTMX attrs for mobile course search (fixes horizontal overflow)
- Remove dead layoutCount var and .m-layouts-pill block in course-cards
- Remove dead 768px breakpoints from players.css (table hidden at 880px)
- Move .mobile-section-head inside else-block for empty state in both
ratings-cards and course-cards (fixes section head showing on empty)
- Add tabindex, role=button, aria-expanded, onkeydown to .m-card and
.m-course-card; toggle aria-expanded in JS toggle functions
- Fix data-history attribute to use <%= (HTML-escaped) instead of <%-
- Convert var to const/let in all new/changed JS blocks
