The mark is the actual brand PNG (already transparent) — just trimmed and
downscaled. The prior version wrongly ran a saturation mask that stripped the
white ring and mangled the wrench into a blob.
- Replace the hand-drawn wrench with the actual hack.build mark: isolate the
pink wrench from the brand PNG onto transparent (public/hackbuild-mark.png)
and use it for the talk tile and the Resources card.
- Showcase grid: 7 columns so the seven projects fill one row, and draw the
hairlines from per-tile borders instead of a grey container showing through
gaps — no more grey empty cells on an incomplete row.
- Drop the now-unused HackBuildIcon.
