explore: mark remixes quietly + credit the original artist
a remixed drawing now reads as one at a glance, in the zds register (subtle
color-mix accent-tinted edge, muted micro-credit — no loud borders):
- the card gets a faint accent-tinted border
- a credit line under the handle shows the ORIGINAL artist (root of the chain,
resolved lazily so the grid never waits), linking to their drawing
- the remix mark is the viewer's own `remix` slot drawing — redraw everything;
it's the same mark as the remix button, defaulting to its label otherwise
