- Detect in-app WebViews (WeChat / TokenPocket / imToken / Telegram / iOS WKWebView, etc.) and show a guide modal asking the user to open the link in their system browser, with a copy-link action.
- For normal browsers, fetch the attachment as a Blob and trigger download from a same-origin object URL so the file always lands in the user's Downloads folder with the original filename, even when the browser would otherwise inline-preview the response.
- Fall back to the anchor download for files larger than 50MB (avoid loading them entirely into memory) or when fetch fails.
- Pass `sizeBytes` from known call sites so the threshold actually applies.
- Add localized strings for the guide modal in all 7 locales.

- Align latest-update media size pills to the Figma spec: 72x24 pill, black background, 24px gray icon cell, 10px label, and the exact small Figma cloud-download SVG.
- For non-document latest cards, remove the duplicate footer download action so media cards only show per-media size/download pills plus the bookmark action, matching the Figma non-document card design.
- Keep card heights flexible so content determines the final card height instead of locking to design mock heights.
- Update desktop header actions to match Figma: remove the standalone desktop favorites button and style the wallet connect pill with the wallet icon while allowing localized labels to expand.
- Replace favorite action with the Figma bookmark SVG and hover state; replace download cloud with the provided Figma SVG.
- Align official recommendation cards with the Figma card structure, colors, and bottom action row.
- Rework popular rows to the Figma desktop rhythm with 90px rows, wide thumbnails, rank area, and right-side action buttons.
- Add a dedicated desktop LatestUpdateCard for Figma-style latest-update masonry cards with flexible text-driven heights instead of fixed card heights.
