What happened

The cho-co documentation platform frontend received a comprehensive visual overhaul across 5 phases. A previous agent had attempted dark mode fixes but introduced a navy-blue colour scheme (#1A1A2E) with purple accents (#7c3aed) that contradicted the entire chocolate factory brand. Badges used a rainbow of unrelated colours. Headings were visually flat. Code blocks displayed raw metadata comments. Version numbers were plain text.

​
What was wrong

Four problems compounded into a UI that looked like a generic SaaS dashboard rather than a Wonka-inspired documentation factory:
  1. Navy dark mode. The dark backgrounds were cold blue-grays — #1A1A2E, #16213E, #0F3460 — which evoke tech dashboards, not chocolate factories. The accent colour was purple (#7c3aed), inherited from a generic design token set called BUNDLE-E.
  2. Rainbow badges. Verified badges were bright green (#40916C), failed were red (#E63946), pending was orange. These looked like traffic lights, not factory output stamps.
  3. Flat headings and typography. All heading levels used the same colour as body text. No warmth, no distinction, no chocolate character.
  4. Broken code blocks. Mock document HTML contained // language: bash and // no-verify metadata comments that rendered as visible text. No syntax highlighting was applied in the read-only view despite lowlight being available.

​
What we did

​
Phase 1: Colour scheme (50+ token changes)

Replaced every navy/purple token with warm chocolate browns and golden accents. Dark mode backgrounds shifted to cocoa tones (#1C1210 deep, #261B16 surface, #3A2A22 muted). The accent colour changed from purple to golden (#D4A843). All syntax highlighting keywords shifted from purple to gold.

​
Phase 2: Badge unification

Verified badges became warm gold (#C9923E) with dark chocolate text instead of white-on-green. The badge now looks like a golden factory stamp.

​
Phase 3: Heading tinting + typography

Introduced a separate --color-factory-heading CSS token that provides warm parchment tint (#F2DFC4) in dark mode — subtly warmer than body text without being obviously coloured. Refined letter-spacing on H1 (-0.03em), increased body line-height to 1.8, and tightened code block font size.

​
Phase 4: ChocoStatus version indicator

Built a new component that replaces plain v5 text with progressive SVG icons: single cocoa bean (v1) → two beans (v2) → chocolate bar outline (v3) → solid bar (v4) → golden shimmer bar (v5+). The golden variant uses the existing shimmer animation.

​
Phase 5: Syntax highlighting

Cleaned all 14 code blocks in mock data — removed // language: and // no-verify metadata comments, added class="language-X" attributes. Created a server-side highlightCodeBlocks() utility that processes HTML through lowlight before rendering. Zero client-side JavaScript cost.

​
Business impact

Before: The dark mode looked like a different product from the light mode. Navy backgrounds and purple accents created visual dissonance with every chocolate-themed element. Technical users would perceive a half-finished product. After: A unified chocolate factory aesthetic across both modes. The warm brown dark mode, golden accents, progressive version icons, and syntax-highlighted code blocks create a premium documentation experience that reinforces the Wonka/factory brand identity consistently. 10 files modified, 3 new files created, build passing.

Action items

  • Visual QA: verify all 7 factory room pages in dark mode
  • Test heading warmth perception — ensure parchment tint is subtle, not distracting
  • Validate WCAG contrast ratios with automated tool (predicted: all passing AA)
  • Consider extending ChocoStatus to the changelog page version entries
  • Explore adding the highlight utility to factory room pages (not just document detail)
