Adds prerendered, JS-less, self-contained error pages for nginx
error_page use — served directly from /var/www/errors/ when the
SvelteKit upstream is unreachable or any nginx-originated 4xx/5xx
fires (including the catch-all default_server for unknown hosts).
- /errors/[status] (DE default) + /errors/en/[status] (EN), each
with a header language toggle linking absolute to bocken.org so
the switch works even on unknown-host fallbacks.
- httpStatus param matcher restricts entries to 401/403/404/500/
502/503/504; entries() drives prerender output.
- generate-error-quotes.ts looks up curated bilingual references
in the existing allioli/drb TSV bibles at prebuild time and
writes src/lib/data/errorQuotes.json.
- build-error-page.ts (postbuild) inlines all CSS, strips module
preloads/scripts, rewrites the home-link to canonical https URL,
and emits .html + .gz + .br per status under build/client/errors.
- deploy.sh syncs build/client/errors → /var/www/errors with
http:http ownership for nginx access.
Split the single OfflineSyncButton into two surfaces with distinct
intents:
- OfflineSyncBanner: dismissable promo on the recipe index that
encourages first-time download (only when standalone + not yet
synced).
- OfflineSyncIndicator: small status pip overlaid on the nav logo
when offline data is available, opening a popover with sync /
clear actions.
Also fold the sync / clear actions into the UserHeader options menu so
the avatar dropdown is the canonical place to manage offline data.
Header.svelte gains a `logo_overlay` snippet slot to host the
indicator pip.
Other:
- manifest.json: prefer the theme-aware SVG as the primary install
icon and drop the redundant 512px raster (kept maskable 192px).
- scripts/deploy.sh: build locally and rsync artifacts to the
server, avoiding any pnpm/git work on the production host.
Bump 1.57.8 -> 1.58.0.
