Card Tones

Render the clawback share card in BOTH tones (neg + pos) as a DESIGN render-only proof — NOT a benchmark result — so the share-card atmosphere (deep-purple LENS_CORE centre, win-only cyan corona, darkened gradients) can be eyeballed in one pass. neg uses a real run's amber regression card (purple core, no corona); pos is a SYNTHETIC fixture built only to exercise the renderer's win branch (purple core + cyan corona) — its number is fabricated, never published. Delegates to the shared preview_card.sh. Use when tweaking the share-card renderer's visuals and you want to see both tones side by side.

File contents

clawback share-card tone proof

Run .skills/card-tones/scripts/preview_card_tones.sh from the project root. It renders the share card in both tones so a renderer change can be eyeballed in one pass. Design proof only — neither card is a publishable result.

.skills/card-tones/scripts/preview_card_tones.sh <neg-run-dir> <out-dir>
# e.g.
.skills/card-tones/scripts/preview_card_tones.sh runs/L0-headline-haiku /tmp/cardcheck

Writes share_card.neg.{png,svg} and share_card.pos.{png,svg} under <out-dir>.

The two cards

neg — a REAL run's amber regression card: the deep-purple core with the corona tone-gated OFF.
pos — a SYNTHETIC win card, built only to exercise the renderer's pos branch (purple core plus the faint cyan corona). It borrows the neg run's bare chart and carries a fabricated positive-token summary purely so the graph and lens-flare compose — the number is a render fixture, never a published metric. Staged in a temp dir and removed on exit.

Depends on

The shared .skills/scripts/preview_card.sh (walks Chrome → sips → SVG-only), which is the single card renderer the preview_card and finish skills also use.
