docs(desktop): tip only when hover teaches something new

Drop the blanket "every icon* button needs a Tip" rule — it produced
tautological kebab tips like "Actions for <row title>". Menu triggers keep
aria-label; tips stay for unlabeled discovery chrome and keybind hints.

-**Icon-only buttons must have a tooltip.** Every button with an `icon*` size

+**Tooltips only when hover teaches something new.** `<Tip>` is for discovery,
+not a tax on every icon. Ask: does hover reveal something the user cannot
+already see or infer? If not, skip the tip; keep an `aria-label` for a11y.
 
-**Keybind hints in tooltips.** When a button corresponds to a rebindable
-hotkey, use `<TipKeybindLabel actionId="..." />` as the `Tip` label — it
-auto-reads both the i18n label and the current keybind combo from the store,
-so the hint stays live when the user rebinds. Pass `text={...}` only when the
-tooltip is context-dependent (e.g. "Show" / "Hide" based on state). Never
-hardcode combos in components — always read from the `$bindings` store via
+Tip unlabeled chrome when the job (or a keybind / truncated path / host /
+other detail) is not already on screen — toolbar / titlebar / statusbar icons,
+`TipKeybindLabel` shortcuts, ownership chips, unlabeled icon grids.
+
+Do **not** tip menu triggers (kebabs / ⋯ / `ActionsMenu` /
+`DropdownMenuTrigger`). The affordance is "open menu"; the verbs live in the
+menu. Never `"Actions for ${row title}"`, `"Project actions"`, `"Actions"`, or
+`"Credential actions"` on a ⋯ — the row already names the thing. Same for any
+control whose visible label already says what the tip would.
+
+Never use native HTML `title=` on buttons — unstyled, ~500ms OS delay, clashes
+with the themed `Tip`. `src/components/ui/__tests__/no-native-title.test.ts`
+fails on any `<button>` / `<Button>` that still carries `title=`.
+
+**Keybind hints in tooltips.** On a tipped button bound to a rebindable hotkey,
+use `<TipKeybindLabel actionId="..." />` — it reads the i18n label and the
+current combo from `$bindings`. Pass `text={...}` only when the label is
+context-dependent (e.g. "Show" / "Hide"). Never hardcode combos; always use
 `useKeybindHint` or `TipKeybindLabel`.
