Vue connected templates keep a string's JS quotes inside bound attributes, so `:title={title}` becomes `:title=""Buy""` rather than a bare identifier; static attributes take plain text. Nested instances no longer lose a boolean `v-if` guard, instance swaps render through `<component :is>`, slot names stay distinct when their idents lowercase alike, slot content CSS reaches the parent stylesheet, and text defaults escape `</script>` in the script block. The five locale catalogs the Vue key rename missed (bn, fi, ka, nl, pl) are updated, and the docs list Leptos/Vue consistently.
