/* proposal.css — the tabbed order page at /proposal.
 *
 * Two tabs (Panel Order / Custom Trim) sit above the forms. The active tab is
 * solid brand green; the inactive one is white. Clicking swaps which form pane
 * is visible — the form styling itself lives in proposal-form.css.
 *
 * Spacing note: the spacing scale only defines 1,2,3,4,5,6,8,10,12,16,20,24.
 * Anything outside that list silently kills the whole declaration.
