 * Penguins on the ice sea, after the team's (unofficial) design: a navy frame, blue links, and primary
 * buttons in a blue close to Idi's body with white text. Navy with orange reads as AWS, so orange is
 * left only to Idi's beak and feet. Workspaces are ice floes and the AI is Idi the penguin.
 * Headings use Zen Kaku Gothic New and body text IBM Plex Sans JP, both self-hosted under /fonts/.
 * Shapes: panels have floe corners (top-left and bottom-right rounder), controls 6px, chips fully rounded.
