+  displayName: I use Arch, btw
+  rulesText: Each card played adds 1 btw until end of turn. C and Rust damage gains +1 per btw. Once per wave, lethal uptime sets Arch to 1 instead and clears btw.
+  flavorText: Compiled from source, emotionally and otherwise.
+  designNotes: V1 base passive. Increment btw before resolving each played card. End of TURN resets btw unless Arch has systemd equipped on-distro. First lethal damage each WAVE consumes rolling-release save, sets uptime to 1, clears btw, and logs a recovery beat.
