- Version compare used positional (index-by-index) list alignment —
inserting one ingredient in the middle shifted every subsequent line
out of alignment, making the whole rest of the list look changed.
Switch to diffArrays (LCS-based) so insertions/deletions are
detected properly; adjacent removed+added chunks still get paired
for word-level diffing so a single edited item doesn't render as a
full delete+insert.
- Translated "Title"/"Description"/"Ingredients"/"Steps" diff section
headers, "Version History" sheet title, compare/restore buttons,
loading/empty states, and the version-detail ingredient/step count
summary (with proper plural forms).
- formatDate() in version history was hardcoded to "en-US" regardless
of the app's locale — now uses the session locale.
- ExportMarkdownButton had no hover tooltip (bare title attribute) —
wrap it in the same Tooltip pattern every other icon button in the
toolbar uses.

Implements the six previously-unscoped feature ideas plus a mobile
layout fix reported via screenshot:
- Mobile: Recipes/Collections/Pantry/Meal Plan/Shopping Lists headers
now stack and wrap instead of clipping buttons on narrow viewports.
- Recipe diff/compare view: word/list diff against any past version,
next to Restore in version history.
- Shared meal plans & shopping lists: new shoppingListMembers/
mealPlanMembers tables (viewer/editor roles, mirrors
collectionMembers), share dialogs, membership-checked routes.
- PDF cookbook export: /print/collection/[id] renders a whole
collection with page breaks, using the existing print-CSS pattern
instead of adding a PDF rendering dependency.
- Grocery delivery handoff: shopping lists can copy-as-text (works
today) or send to Instacart once INSTACART_API_KEY is configured
(stub adapter — real API needs a partner agreement).
- Personalized "For You" feed tab: ranks public recipes by tag/
dietary overlap with the user's favorited/highly-rated history.
- PWA: added manifest.json + icons on top of the existing service
worker so the app is installable; cook-mode pages were already
cached for offline use.
