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.

- Substitute finder never applied the user's BYOK/admin AI key (only fell
back to raw process.env), so it silently failed whenever the key was
stored via settings rather than a literal env var. Now resolves via
getDefaultProviderWithKey like every other AI route. Popover also
surfaces real error messages instead of swallowing failures.
- Ingredients with quantity 0 (salt, pepper, "to taste") rendered the
literal digit "0" in cooking mode, print view, public recipe page,
shopping lists, and serving scaler — several sites relied on generic
truthiness/filter(Boolean), which doesn't catch a stored "0" string.
Added a shared hasQuantity() helper and applied it everywhere quantity
is rendered, plus in the AI recipe-chat context sent to the model.
- Recipe chat panel rendered a duplicate close button on top of shadcn
Sheet's own built-in close X, producing a garbled overlapping glyph.
Removed the duplicate.
- Recipe chat assistant replies are markdown from the model but were
rendered as raw text; added react-markdown so formatting actually
renders.
