Human comments

What was wrong

On phones, "Send download link" shared whatever page the visitor was on, so the computer could open a guide or plugin page instead of a download. The result of the share wasn't recorded. Guide heroes and the footer still offered Mac installers on phones. "Windows (Alpha)" streamed an .exe to phones. /marketplace and /changelog had no phone install path.

What changed

• The shared link is now the homepage, which shows the right download for the computer that opens it.
• The link keeps the page's utm_*, gclid, gbraid and wbraid parameters, and adds a fixed via=share marker.
• The marker appears in the computer's pageview URL and in the download event's referrer, with no new plumbing.
• A new landing_send_to_computer_result event records shared, cancelled, copied or copy_failed per placement.
• On touch devices, guide heroes show "Send download link" instead of "Download for macOS".
• On touch devices, the footer Download link and the "Windows (Alpha)" link are hidden.
• /marketplace and /changelog show the send button on touch devices, with new marketplace and changelog placements.
• Both versions stay in the markup and CSS picks one, so desktop looks the same and phones see no flash.

How you verified

• New unit tests cover the shared URL, parameter preservation, the marker and the Global Privacy Control case. They pass.
• New unit tests cover all four result outcomes and the click-to-result event pair. They pass.
• New render tests check the desktop and touch markup on install options, guide hero, footer and marketplace. They pass.
• The download endpoint test confirms via=share survives in $referrer.
• @bb/web tests, typecheck and lint pass locally.
• No real-device or browser check yet.
• Remote CI passed on d868db7.
