A new writer's first copy used to draw a coloured box. template-map-a.vue now
draws the points in data/places.geojson on a basemap with one translated title,
through the library's own pieces (useMapInstance, resolveMapProvider, labelFont,
emissivePaint). It follows the page's engine, locale (right-to-left included) and
token, and with no token it runs on keyless MapLibre, so it works with no account.
template-map-b.vue stays as the second-screen example, so the README, the tutorial
and the plugin-designer skill (rename a, delete b) stay true. The README gains the
map's pieces table and the dx-maps paths.
Library change: library/i18n/locales/<11>/template.json (key template.title) is
eagerly globbed into every bundle, so consumers need rebuilding (rule 5B).
