+/**
+ * BackLink — small "← Page" navigation cue that sits above a page's
+ * `<h1 className="accent-rule">` heading.
+ *
+ * Why this exists
+ * ---------------
+ * The pattern was originally written inline on /team and /dashboard/new
+ * as `<Link className="inline-flex …"><span>←</span> Title</Link>`.
+ * That's wrong because `.accent-rule` (defined in globals.css) sets
+ * `display: inline-block` on the H1 — so an inline-flex link followed by
+ * an inline-block H1 are both inline-level, and end up on the same
+ * baseline whenever there's horizontal room for them. The `mb-4` on the
+ * link does nothing because vertical margin between inline boxes
+ * doesn't push siblings to a new line.
+ *
+ * Solving it: this component renders the link as a block-level flex
+ * container with `w-fit` so it shrinks to its content (and its hover
+ * area doesn't span the gutter). The trailing block element below sits
+ * cleanly on its own line.
+ *
+ * Use it whenever a page has a back-link above an `accent-rule` H1.
+ * The two prior callsites (/team and /dashboard/new) have been
+ * migrated; new pages should just use this directly.
