fix: purge AI slop from judgment essay, add voice linting pipeline

Browse Source 
- Killed 16 em-dashes (Claude fingerprint, 15.9/1000 words -> 0)
- Replaced all clause-dash-elaboration patterns with periods, colons, restructuring
- Removed 'The One-Sentence Version' section (restated the intro, voice anti-pattern)
- Broke tricolon at lines 56-58 (too-clean parallel structure)
- Collapsed 'How to Actually Help' listicle into connective prose
- Added receipt link for ~100x inference cost claim
- Heading dashes replaced with colons (Tradesman Analogy, Excellence vs Functional)

New tooling:
- scripts/lint-voice.sh: mechanical anti-slop linter (em-dashes, trigger words,
  hedging, filler, receipts, sentence uniformity)
- .amplifier/skills/voice-check/SKILL.md: LLM-as-judge voice authenticity check
  (8 dimensions against VOICE.md profile)
- .amplifier/AGENTS.md: standing rule requiring both checks before any publish

# Design Token System — Crash Test Dev
## User's Spark (preserved)
> A well-used workshop. Not a pristine showroom — the one where someone actually builds things.
> Tools are organized because disorganization wastes time. The wood has warmth.
> The light is good because you need to see details. There's a coffee cup somewhere.
**Metaphor:** The workbench, not the gallery.
**Materials vocabulary:** Paper, ink, wood, stone, iron.
**Personality:** Dry warmth. Quiet confidence. Evidence over performance.

"rationale": {
"colorPhilosophy": {
"title": "Why these specific colors",
"explanation": [
"The surface-base (#F5F0E8) was tuned to sit precisely between 'warm' and 'yellow.' Its RGB channels (245, 240, 232) taper from R→G→B, placing the warmth in the red channel without letting it become cream or beige. It reads as 'good light on heavy paper' — the brief's exact intent.",
"Text-primary (#2B2421) avoids the blue-black of browser defaults (which typically live around #1a1a2e or #333). The brown-black comes from keeping R > G > B at the dark end: (43, 36, 33). This is ink with warmth, not ink with coldness.",
"The accent-primary (#A0522D, CSS 'sienna') is a historically grounded earth pigment — literally fired earth. At 4.95:1 contrast on base, it passes AA for body text and works as link color without being 'red' or 'alarming.' The hover state (#8B4726) darkens toward the earth rather than toward black.",
"Accent-secondary (#7D6C2F) captures tarnished brass — the green-gold of aged copper alloy, not the bright gold of decoration. It needed darkening from the first candidate to meet AA (4.56:1), but the constraint improved the color: real tarnished brass IS darker than you'd first guess.",
"State colors (success, warning, error, info) were designed within the warm palette. No saturated primaries. Success uses sage-moss (#4A5E3A on #E8EDDF), warning uses amber (#7A5C1F on #F2E8D0), error uses deeper terracotta (#8B3A2A on #F2DED6). Even the info state avoids blue entirely — it's warm neutral (#4A4540 on #E5E2DA)."
]
},
"contrastStrategy": {
"title": "How we exceeded WCAG requirements",
"explanation": [
"The brief demanded WCAG AAA (7:1) for body text on base. We achieved 13.44:1 — nearly double the requirement. This provides comfortable reading even in imperfect lighting conditions or on devices with lower contrast ratios.",
"Secondary text at 5.46:1 (AA requires 4.5:1) gives comfortable headroom. Tertiary text at 3.04:1 meets AA-UI (3:1) — appropriate since it's used only for supplementary information like timestamps and tags, never for essential content.",
"Code text (#3D342E) on the code surface (#EEEAE2) achieves 10.12:1 (AAA). Code is evidence — it must be maximally readable.",
"Border tokens are split into three tiers: subtle (decorative, no contrast requirement — the 'score line'), default (separators), and strong (#8E857A at 3.20:1, for functional UI elements). This acknowledges that a publishing site's dividers are decorative, not interactive, while still providing accessible borders when needed."
]
},
"typographyRationale": {
"title": "Three voices, mathematically grounded",
"explanation": [
"The Major Third ratio (1.25) was chosen because the brief explicitly asked for conservative hierarchy. At 1.25, the jump from body (18px) to H4 (22px) is perceptible but not dramatic — the family change from serif to sans does most of the work. Weight and family, not size, create the hierarchy.",
"Heading sizes round to clean values: 22, 28, 36, 44px. Each pair's ratio stays within 1.17-1.29 of true Major Third — close enough for mathematical coherence, rounded enough for pixel clarity.",
"The 18px body base was set by the brief, and it's correct for sustained technical reading in a serif face. At 1.125rem, it inherits browser zoom gracefully.",
"Code at 16px (1rem / 0.9em of body) respects the 'different register' described in the aesthetic guide. JetBrains Mono at 16px with 1.6 line-height gives comfortable code reading without competing with the prose voice.",
"Letter-spacing uses negative tracking for headings (-0.02em at h1, tapering to -0.005em at h4) because Inter at display sizes needs tightening to feel intentional. Body prose and code use normal tracking — the fonts were designed for these sizes.",
"Blockquote at 20px italic is the only off-scale value — sitting between base (18) and lg (22). This is deliberate: a pull quote should feel like a different register, not a heading. The italic + size shift + left border treatment (defined in spacing) makes the voice unmistakable."
]
},
"spacingRationale": {
"title": "Book typography meets code breakout",
"explanation": [
"The 8px grid provides the full range from fine-grain (4px component padding) to macro (96px section spacing). All semantic tokens map onto grid multiples.",
"H2 above-spacing (64px / 4rem) creates the 'chapter break' the aesthetic guide describes. At nearly 4x the paragraph gap, it creates a decisive pause in the scroll. H2 below-spacing (16px / 1rem) is deliberately tight — the heading belongs to what follows, not what precedes it.",
"Paragraph gap (24px) is ~1.33em at 18px base — within the 1.2-1.5em range specified, and landing on the 8px grid (3x base).",
"Code block vertical margin (40px / 2.5rem) positions code as 'exhibited artifacts' — clearly separated from prose without creating visual gaps. The 3px left accent line in terracotta signals the register change from narrative to evidence.",
"The prose column at 720px (45rem) produces ~65 characters per line at 18px Source Serif 4 — the typographic sweet spot for sustained reading. Code breaks to 840px (52.5rem) creating the narrow-wide-narrow rhythm described in the aesthetic guide."
]
},
"borderRadiusRationale": {
"title": "Worn edges, not machined radii",
"explanation": [
"Four meaningful stops: 2px (inline code), 4px (code blocks, buttons), 6px (cards), 8px (larger panels). The progression feels like increasingly worn edges on workshop materials — slight softening, never roundness.",
"No radius exceeds 8px except 'full' (pills/avatars). Nothing on this site should look like a mobile app button or a glassmorphism card."
]
},
"motionRationale": {
"title": "Fast, barely-there, respectful",
"explanation": [
"150ms is the site's default transition — fast enough to feel instant, slow enough to not be jarring. Color transitions (hover, focus) at 100ms. Layout transitions at 250ms (rare — this is a reading site, not an app).",
"prefers-reduced-motion reduces all durations to 0ms, no exceptions. This is non-negotiable.",
"Only GPU-accelerated properties (transform, opacity) should be animated. Color transitions are the exception — they're so fast (100ms) that the CPU cost is negligible."
]
},
"whatWeDidNotDo": {
"title": "Intentional omissions",
"explanation": [
"No dark mode tokens. The aesthetic guide explicitly says 'Ken's work happens in daylight.' Dark mode can be added later if needed — the semantic naming makes it straightforward.",
"No elevation system. The brief says 'nothing floats.' Two shadow tokens (sm, md) are the maximum depth vocabulary.",
"No animation choreography. A publishing site doesn't need entrance animations, scroll-triggered effects, or page transitions. Links change color. That's it.",
"No breakpoint tokens. The layout is a single column that narrows gracefully. The prose column (720px) and code breakout (840px) handle their own responsive behavior within the 1100px container.",
"No z-index scale. Nothing overlaps. The page is flat paper with ink on it."

## Success Criteria
- **Functional:** All tokens resolve to concrete CSS values. Zero undefined variables.
- **Aesthetic:** Every color reads warm. The page feels like paper and ink under good light.
- **Accessibility:** AAA body text (13.44:1), AA secondary (5.46:1), AA accent links (4.95:1). All verified.
- **Performance:** Three fonts, minimal weights. No heavy shadow/blur calculations.
- **Longevity:** Nothing here will look dated in 5 years. Paper, ink, and careful spacing don't go out of style.
