**Duration:** 3 min - **Started:** 2026-02-27T23:08:00Z - **Completed:** 2026-02-27T23:10:32Z - **Tasks:** 2 - **Files modified:** 10 ## Accomplishments - Built complete two-tier CSS token architecture: 45+ primitive tokens (colors, neutrals, gradients) aliased through 17 semantic color tokens - Registered all semantic tokens with Tailwind v4 via @theme inline for utility class generation (bg-primary, text-secondary, font-mono, etc.) - Installed and bundled Fira Code (4 weights) and Share Tech (1 weight) via Fontsource with zero external CDN dependency - Created glow effect tokens with 5-step blur scale, 3-step spread scale, and 4-tier interaction-state intensity multipliers - Added surface transparency tiers, transition durations, border radii, and spacing scale tokens - Set static data-theme="cyberpunk" on HTML element and color-scheme meta for FOUC prevention ## Task Commits Each task was committed atomically: 1. **Task 1: Install Fontsource packages and create font import module** - `aeacd1a` (feat) 2. **Task 2: Create the four token CSS files and theme entry point** - `7542334` (feat) ## Files Created/Modified - `src/theme/primitives.css` - Raw color values (cyan, magenta, red, lime, green palettes), neutral gray scale, void gradient stops - `src/theme/semantic.css` - Semantic aliases mapping to primitives, @theme inline Tailwind registration, cyberpunk theme definition - `src/theme/typography.css` - Font family tokens, 8-step type scale, line heights, font weights, letter spacing - `src/theme/effects.css` - Glow blur/spread/intensity tokens, surface transparency tiers, transition durations, border radii, spacing scale - `src/theme/index.css` - Theme entry point importing all token files in dependency order - `src/theme/fonts.ts` - Fontsource side-effect imports for Fira Code (400-700) and Share Tech (400) - `src/App.css` - Updated to import theme after Tailwind, replaced hardcoded values with token references - `src/index.html` - Added data-theme="cyberpunk", color-scheme meta, inline background for flash prevention - `src/index.tsx` - Added fonts.ts import before App.css - `package.json` - Added @fontsource/fira-code and @fontsource/share-tech dependencies ## Decisions Made - Token prefix convention: `--hh-raw-*` for primitives (never used directly by components), `--hh-*` for semantics (component-facing) - Font stack: Fira Code monospace for body text and code (cyberpunk terminal aesthetic), Share Tech sans for display headings - Glow intensity follows interaction hierarchy: default(0.3) < focus(0.45) < hover(0.65) < active(0.9) for restrained premium feel - Import order enforces dependency chain: primitives -> effects -> typography -> semantic ## Deviations from Plan None - plan executed exactly as written. ## Issues Encountered None. ## User Setup Required None - no external service configuration required. ## Next Phase Readiness - All design tokens available as CSS custom properties under :root and [data-theme="cyberpunk"] - Tailwind utility classes (bg-primary, text-secondary, font-mono, font-display, etc.) ready for component usage - Token infrastructure ready for Plan 02-02 (token audit and visual verification) - Future themes can override semantic tokens under alternative [data-theme] selectors ## Self-Check: PASSED All 9 created/modified files verified on disk. Both task commits (aeacd1a, 7542334) found in git log. SUMMARY.md exists. --- *Phase: 02-theme-system* *Completed: 2026-02-27*
