markxShare page CTA · Option A
Read-only link (/s/$token) for anonymous viewers. Goal: make them want their own board. Option A is the pick, shown at 1440 desktop and 390 mobile on a replica of the real share board. B and C stay below for reference. Logged-in viewers keep "Duplicate to my workspace" in the same slot.
Top-right pill, twin of the title chip
Same glass chip as the title (white 85%, blur, hairline). markx logo · markx · Make your own →, using the app's topbar logo (2×2 tiles). Mobile: logo (20px) + Make yours, 44px tall; the title truncates first so they never collide. Always visible, never covers the board. Fades in 700ms after load.
Alternatives (not picked)
Bottom-centre “Made with markx” pill
Floating surface like the app's menus. Desktop: Made with markx · Create a free board →. Mobile: full-width bar, safe-area aware, 40px button inside a 52px bar. Reads as a badge, so it's quieter, but it sits on top of the cards and near the phone's browser bar.
Idle card after a few seconds
Small card bottom-right (mobile: bottom sheet-style card). Collect your own references + one line + Create your board / Not now. Shows once per session after ~8s or the first pan, dismissible, remembered in sessionStorage. Strongest pitch, but it interrupts. (Mock shows it at 1.6s and re-shows after dismiss so you can replay.)
