Token Alignment Report: Design System ↔ Production
This documents how the Storybook design system tokens map to production's Tailwind config.
Approach
- Where tokens match — production's naming and values adopted directly
- Where Storybook adds tokens — added alongside production's existing tokens
- Where there's a conflict — flagged below for review
Colours
Adopted from production (unchanged)
| Production token | Hex | Notes |
|---|---|---|
grey-1 |
#f4f3ef | |
grey-2 |
#D7E1E2 | Matches sage-200 |
grey-3 |
#b9c7c9 | Matches sage-400 |
grey-4 |
#4c5459 | Matches sage-800 — default body text |
grey-5 |
#4c5b6b | Matches sage-700 |
grey-6 |
#D9D9D9 | No design system equivalent |
grey-7 |
#EEEEEE | No design system equivalent |
color-1 |
#B0610F | Matches brand-600 |
color-1H |
#9e6f42 | No exact DS match (between brand-600 & brand-500) |
color-2 |
#DCC1A6 | Close to brand-200 (#EBDAC8) — slightly warmer |
color-2H |
#d1b79e | No exact DS match |
color-3 |
#BA834E | Matches brand-500 |
color-4 |
#D0A070 | Matches brand-400 |
color-5 |
#F4F3EF | Same as grey-1 |
color-6 |
#51301B | Matches brand-900 |
action-orange |
#F89E53 | No DS equivalent — unique to production |
success-green |
#76B041 | Different from DS green-500 (#4A8F4A) |
warning-red |
#A41623 | Different from DS red-600 (#BC2F2F) |
Design system palettes added alongside
Full 11-shade palettes: brand, sage, neutral, red, amber, green, blue
These are available as Tailwind classes: bg-brand-500, text-sage-800, etc.
Flagged conflicts — resolved
Strategy: Keep both production and DS values. Production names preserved for backward compatibility; DS names are the go-forward standard. New components should use DS token names. Inline comments in tailwind.config.js document the mapping.
| Issue | Production | DS equivalent | Resolution |
|---|---|---|---|
color-2 vs brand-200 |
#DCC1A6 | #EBDAC8 | Both kept. Warmer production value used in existing templates; DS value for new components. |
color-1H hover |
#9e6f42 | — | Kept. Superseded by DS interactive hover states (brand-700) as components migrate. |
color-2H hover |
#d1b79e | — | Kept. Same approach as color-1H. |
success-green vs green-500 |
#76B041 (lime) | #4A8F4A (forest) | Both kept. Visually different; new components use DS green-* palette. |
warning-red vs red-600 |
#A41623 (crimson) | #BC2F2F (warm red) | Both kept. New components use DS red-* palette. |
action-orange vs amber-400 |
#F89E53 | #ffb833 | Both kept. Production-only orange retained; closest DS equivalent is amber-400. |
grey-6, grey-7 |
#D9D9D9, #EEEEEE | ~neutral-300, ~neutral-100 |
Both kept. Close but not identical; production values retained for existing usage. |
Typography
Font families — aligned
| Production | Design system | Status |
|---|---|---|
font-sans (Montserrat) |
fontFamily.body |
Aligned |
font-notoSerifSC |
fontFamily.display |
Aligned |
font-arial |
— | Production only |
Font sizes — mixed
Production has custom sizes (xxs, 1.5xl, 2.15xl, 2.3xl, 3.3xl) that map to specific Tailwind typography classes. Design system has its own scale (2xs–4xl). Both are included in the config.
Typography classes
Production's .tailwindcss-h1 through .tailwindcss-h6 classes use hardcoded #4C5459 text colour. Design system uses MUI Typography variants that reference tokens. Both can coexist — MUI components use the theme, Tailwind templates use the classes.
Breakpoints — fully aligned
| Name | Value | Source |
|---|---|---|
xs |
0px | Both (MUI default) |
sm |
600px | Both (MUI default) |
md |
960px | Both (MUI v4 default) |
lg |
1280px | Both (MUI default) |
xl |
1536px | Both (MUI v5+ default) |
Spacing — compatible
Production's custom spacing (5px, 12px, 12.5px, 14px, 15px, 30px) is preserved as padding and margin extensions. Design system's 4px-base scale is available as standard Tailwind spacing utilities.
Conclusion
The merged tailwind.config.js provides full backward compatibility with production's existing classes while adding the design system's semantic palettes. All 7 flagged colour conflicts have been resolved with a "keep both, document mappings" strategy — production values are preserved for backward compatibility, DS values are the go-forward standard, and inline comments in the Tailwind config document the mapping between them.
