+ * SiteFooter — a single slim row carrying the feedback link. Mounted in
+ * both (app) and (legal) layouts so the affordance follows the user
+ * everywhere on the site without taking up perceptible vertical space.
+ *
+ * No wordmark, no about / privacy / terms links, no dedication line —
+ * those live in settings and the legal pages themselves. This footer
+ * exists solely to keep "send us feedback" one tap away from anywhere.
