/**
 * LeetCode topic-tag slug → the campaign landing routes that teach it, in
 * default preference order. The one answer to "does the campaign cover this
 * tag", read by two sides that must agree:
 *
 * - `components/ProblemBadges.astro` links a covered tag's badge to its
 *   landing page, and every other tag's badge to `/guides/<slug>`;
 * - `apps/cli/sync.ts` creates a placeholder `content/guides/<slug>.mdx` for
 *   every tag a problem page carries that is NOT a key here.
 *
 * Add a key when a campaign topic starts teaching a tag; its guide page is then
 * dead weight, delete it by hand. A tag naming two topics (DFS/BFS: tree and
 * graph; DP: 1-D and grid) lists both; the badge picks per page.
