Specializations move from a 340px left rail to a horizontal 2-row chip
grid at the top (drag L→R to rank). Each chip shows rank, spec-colored
abbreviation tag matching the tags used in plans/schedule, full name on
its own row, status glyph, and a micro credit bar. Hover/tap a chip to
see full status, allocated/threshold credits, and contributing-courses
breakdown in a popover.
The right pane splits into two side-by-side columns on desktop: Top
Plans (left) and Schedule (right), each scrolling independently. The
search progress bar hoists into a global strip below the spec grid so
it stays visible regardless of which column is scrolled.
Schedule blocks render their course choices as a horizontal row of
equal-width buttons (3-5 per set) instead of stacked rows. Pinned sets
collapse to a single line with the course name inline next to the set
title. Term headers (Spring/Summer/Fall) remain as section dividers.
On mobile, the layout becomes a 3-tab segmented control
(Specializations / Plans / Courses) with the search progress strip
above the tabs. The previous floating MobileStatusBanner and
MobileCourseBanner are dropped — tabs replace their navigation
function.
