/* carbon-thin.css — house brand overlay on top of nes.css
 *
 * Lightweight DArnTech brand layer that sits over nes.css's NES aesthetic.
 * "Carbon-thin" per operator phrasing 2026-05-25: dark-themed minimal chrome
 * applied THINLY, not as a competing visual system. nes.css does the heavy
 * retro lifting; this file just tints + spaces + adds the wordmark treatment.
 *
 * Per [[frontend_stack_nes_css_retro_calendar]] — study the proxmox-homelab
 * retro frontend (~/projects/proxmox-homelab/frontend/) as reference for
 * idiom, build fresh here.
