Renders a shareable “before lean-ctx” SVG card from a discover analysis — the
“ghost tokens you’re leaving on the table” framing that drives the first-run share
loop. Same 1200x630 social-card dimensions and visual language as the Wrapped card,
but in an amber/red “leak” palette. Pure string building; all data-derived text is
XML-escaped. Aggregate estimates only — never command contents or arguments.
