Backend keeps every guest's modal payload (details, backups, apps, schedule, mount points) warm in-memory and exposes them through a single `/api/vms/modal-cache-all` endpoint. The dashboard hydrates its entire modal cache from that one request on page load, so opening any guest — first click or after coming back later — renders instantly. Replaces ~84 per-guest fetches with 1.
## i18n
- Swedish (sv) wired end-to-end: `MESSAGE_CATALOG` in `provider.tsx` now imports `sv/common.json`; `SUPPORTED_LANGUAGES` reordered as English + alphabetical native and all eight locales marked complete.
- Settings → Interface language: the per-locale status cards grid is retired now that all eight locales are populated end-to-end; the dropdown selector is the only control.
- CLI change-language dialog (`scripts/menus/config_menu.sh`) picks up Swedish and matches the Monitor ordering.
- Spanish catalog: label polish across the dashboard — *VM y LXC activos* / *11 VMs* / *11 detenidos*, LXC modal tabs shortened to *App / Actualiz. / Montajes / Copias*, *Limpiar / Cerrar* replacing the wrong *Claro / Cerca* in terminal controls, *En ejecución / Ejecutar* replacing the literal *Correr*.
- Cross-locale normalisation across ES / DE / FR / IT / PT / SK / SV: *OK* / *Proxmox System Dashboard* / *Warn* labels stay consistent, *AVG / MAX / MIN* kept verbatim as universal abbreviations so the stats row no longer overflows.
- Tailscale brand preserved verbatim across ES / FR / IT / PT — previous machine-translated variants like *"escala trasera"* / *"à grande échelle"* restored.
## Docs
- `ROADMAP.md` rewritten as a short invitation to the [ProxMenux Roadmap project board](https://github.com/users/MacRimi/projects/1). `ROADMAP.es.md` removed — it mirrored the same outdated version-milestone plan and the docs site keeps the Spanish surface for users who need it.
- `release.md` annotated with nine pending sections for the v1.2.4.1 beta cycle.
## AppImage
- `ProxMenux-1.2.4.1-beta.AppImage` replaces the previous `ProxMenux-1.2.4.AppImage`. Sidecar `ProxMenux-Monitor.AppImage.sha256` regenerated.
Rebuild of the 7 supported translation catalogs (ES/DE/FR/IT/PT/SK/SV) covering Monitor (`AppImage/messages/<lang>/common.json`, 3903 keys each) and CLI (`lang/<lang>.json`, 5272 keys each). Swedish (sv) is added as a new locale end-to-end.
Two related changes to the translation infrastructure:
1. Add Swedish (sv) as a supported locale in both the CLI and Monitor
translation systems. Inspired by PR #121, which arrived before the
current auto-generated cache layout existed.
2. Include Slovak (sk) in the default auto-fill target set. Guardrail #1
in build_i18n_messages.py never overwrites a key whose target value
differs from EN, so Vaso73's curated Slovak strings stay intact —
auto-translation only fills keys that are still on the English
fallback. Trade-off accepted: sk users see decent machine translation
for new keys immediately instead of raw English while human curation
catches up, and Vaso73 keeps full ownership of the wording via
follow-up PRs.
Changes:
- AppImage/lib/i18n/languages.ts: add "sv" to LanguageCode + register
in SUPPORTED_LANGUAGES.
- AppImage/messages/sv/common.json: stub — will be filled by the i18n
workflow on the local bootstrap.
- .github/scripts/build_translation_cache.py: add "sv" to
DEFAULT_LANGUAGES.
- .github/scripts/build_i18n_messages.py: add "sk" and "sv" to
DEFAULT_LANGUAGES; update comments to explain the sk decision.
- .github/workflows/build-i18n-messages.yml: default input includes
sk + sv; comments updated to match.
Localize runtime labels for SMART/NVMe details, backup target badges, firewall interface types, settings units, and generated health status copy while keeping the English and Slovak catalogs in key parity.
Move Monitor dashboard UI copy into translation keys and expand the English source catalog across the main pages, modals, and shared AppImage components.
Add the Monitor dashboard i18n provider, supported language metadata, message catalogs, fallback behavior, and the initial language selector/wiring for the AppImage UI.
