From abc4c4a2638f4f366f4f99cd72ba64a8c8957a2e Mon Sep 17 00:00:00 2001 From: Stardream Date: Mon, 20 Apr 2026 18:28:51 +1000 Subject: [PATCH] feat(Bangumi_Topic_Share): add share card script with copy/download/text actions New userscript for Bangumi topic pages. Generates a styled share card via html2canvas, with icon buttons to copy image to clipboard, download image, copy share text, or close the overlay. Button placement moved to the stable #columnInSubjectB sidebar to avoid conflicts with other components.
