   Vibe Dashboard v2 — shared modal primitive (design-upgrade row C47)
   One backdrop + one panel for every dashboard modal. Reads styles/vibe-tokens.css
   only — never hardcode hex here. Consumers: src/dashboard/code-overwrite.jsx
   (signing overlay). Pending adoption: tasks.jsx / network.jsx (S4),
   login.jsx wallet chooser (S7); legacy duplicate styles/dashboard.css:1290-1341
   (S8 closes it).

   .v2-modal-backdrop            fixed, full-viewport scrim (--v-scrim + blur 4px),
                                 grid-centred, z-index 80, fades in.
   .v2-modal-backdrop.is-local   absolute — covers only the nearest positioned
                                 ancestor (a card), z-index 5, inherits its radius.
   .v2-modal                     the panel: --v-surface, --v-border, --v-r-modal,
                                 28px padding, min(520px, 100%), lifts in.
   .v2-modal.is-plain            no panel chrome — centred text straight on the
                                 scrim (the signing overlay).
   .v2-modal.is-sheet            ≤640px: bottom sheet on --v-sheet, top radius only.
   .v2-modal-close               32px round icon button, top-right of the panel.
   .v2-modal-kicker / -title / -body / -actions   panel typography + button row.

   Conventions (the CSS cannot do these — every consumer must)
   ----------------------------------------------------------
   • root element: role="dialog" aria-modal="true" aria-labelledby=<title id>
     (an in-flight status overlay uses role="alertdialog" aria-live="assertive").
   • Escape closes/cancels: add a keydown listener while open, remove on close.
   • Focus: use window.V2ModalTrap(active, panelRef) (a React hook, defined in
     src/core/modal-trap.jsx) — it focuses the first control (or the
     panel, tabIndex=-1), cycles Tab / Shift+Tab inside the panel, sets `inert`
     on everything outside the panel's ancestor chain, and restores focus to
     the opener on close.
   • Background clicks on .v2-modal-backdrop close a dismissable modal; a modal
     that guards an in-flight action (signing) offers an explicit Cancel instead.
   • Reduced motion: the entry animations are disabled below.
