style: humanize the pixel operator marker

[xnoto]

Summary

Refines the koan marker from an agentic operator shape into a 16×16 pixel human seated at a workstation: distinct head/hair/face, torso/arm/leg, chair, monitor, screen, desk, and keyboard. The person uses the muted-text token, workstation uses the faint-text token, and cutouts use the page background. The inline SVG remains aria-hidden, textless, static, and asset-free.

The koan, divider, title, portal links—including the canonical OpenCode destination—PWA behavior, metadata, and all other portal content remain unchanged.

Fixes # — not applicable; owner-requested visual refinement.

Type of change

• Bug fix
• Feature / enhancement
• Documentation
• Infrastructure (OpenTofu root or module)
• GitOps desired state (manifests, kustomize, charts, SOPS/KSOPS secrets)
• Container image
• CI / reusable workflow
• Refactor / cleanup
• Breaking change

Validation

• Required pull-request checks pass
• Generated or centrally distributed files were regenerated by their owning automation, not hand-edited (not applicable: source-only HTML/CSS refinement)

Pull-request CI will run static pre-commit checks, including prettier and gitleaks, plus node --check makeitwork.cloud/sw.js. No deployment preview exists; live desktop and mobile visual validation remains post-merge.

Impact and rollout

Self-contained in makeitworkcloud/www: only makeitwork.cloud/index.html changes. No producers, generated copies, PWA behavior, service worker, metadata, links, assets, or the onion site change. After an owner-approved merge, deploy.yml automatically syncs both site directories to S3 with delete semantics and purges Cloudflare. Rollback is a revert followed by the same automatic deployment.

Safety and secrets

• Contains no plaintext secrets, decrypted SOPS values, state files, kubeconfigs, tokens, or private endpoints
• No local OpenTofu init/plan/apply/destroy/import/state operations were run or claimed — plans come from pull-request checks
• Breaking or irreversible effects are described above with rollback notes
