/* Octa Network, octanet.online
   Decisions, kept on purpose:
   - Type: IBM Plex Sans (variable, the narrow width for headings), IBM Plex Mono
     only for prices and figures. Self-hosted: Google Fonts is unreliable from RU.
   - Colour: neutral near-black, warm off-white text. Brand indigo is flat and
     only marks the main action and links. No gradients, glows or coloured shadows.
   - Shape: one 4px radius, hairline rules instead of cards where possible.
   - Motion comes from the ASCII renders (assets/media, tools/ascii-studio). */
