CI failure root cause

yarn build fails with:

Requires Babel "^7.0.0-0", but was loaded with "8.0.1"
(While processing: ".../@vue/cli-plugin-babel/preset.js")

This PR only bumps @babel/core 7 → 8, but babel.config.js still uses @vue/cli-plugin-babel/preset. That package depends on Babel 7 (@babel/core ^7.12.16 / @babel/preset-env 7.x) and asserts a Babel 7 API version, so the build breaks as soon as core is 8.x.

Recommendation: skip / close this PR

Babel 8 is not a drop-in upgrade here:

1. Vue CLI babel stack is Babel 7-only — @vue/cli-plugin-babel 5.x has no Babel 8 support (Vue CLI is maintenance-mode).
2. Isolated major bump — Dependabot only changed @babel/core; a real migration needs replacing the Vue CLI preset with @babel/preset-env 8 (and related polyfill changes — Babel 8 removed useBuiltIns from preset-env).
3. Broader migration work — .browserlistrc still targets IE 10, and Babel 8 changes default compile targets / ESM defaults; that should be an intentional migration, not an automerge.

Babel 7 remains supported for security until June 2027, so staying on 7.x for now is fine.

When ready to adopt Babel 8: drop @vue/cli-plugin-babel, point babel.config.js at @babel/preset-env 8, review browserslist/polyfills, then bump @babel/core.

I'll open a small follow-up to ignore @babel/core major updates in Dependabot so this doesn't keep failing CI.

[hellopablo]

Follow-up: happy-path Babel 8 migration is in #216 (swap off @vue/cli-plugin-babel, browserslist → defaults). Once that merges, this Dependabot PR can be closed as superseded.

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
