A test pins the variant deck: Like and Dislike are drawn only for someone who can vote, and each form posts to a route that accepts it

src/web/pages/variants.ts draws one card per open sibling pull; no test imports it.

Done, in test/variant-deck.test.ts:

[ ] A writer sees a card per open pull in the group, each with Like and Dislike forms carrying the CSRF/same-origin shape the other forms use.
[ ] A reader without write and a guest see the cards with no vote forms.
[ ] Submitting the Dislike form as the writer closes that pull and the deck then lists one card fewer.
[ ] A closed or merged sibling is not drawn as votable.

Files: test/variant-deck.test.ts; src/web/pages/variants.ts only if a case is red. Suggested: scout.
