+// `Drink`/`Bar` come from @wutzcalc/shared — the tablet code already did
+// this, but Admin.tsx used to re-declare its own near-identical copies,
+// which had already drifted (its local Drink.archived was typed `number`
+// while the shared one was `boolean`, even though both describe the exact
+// same wire field). BarRow/stats shapes below are admin-only — not part
+// of the wire contract the tablet also consumes — so they stay local.
