How Kinetic Typography / Viewport Stretcher and Dark Premium solve the same 7 structural design dimensions differently. Every observation is cited to a specific captured specimen in the vault.
Kinetic Typography / Viewport Stretcher
Variable font axes (`wdth` 50..150, `wght` 200..900) are driven directly by scroll velocity and pointer X/Y coordinates so the headline stretches edge-to-edge (`100vw`) as a kinetic accordion.
133-dia-studio-kinetic-variable-type-identity-system · DIA Studio — Kinetic Variable Type Identity System
Display masthead uses `font-size: clamp(4.5rem, 16.5vw, 22rem)` with `line-height: 0.84` and `-0.04em` tracking so the wordmark physically locks to both left and right viewport edges.
134-studio-freight-darkroom-viewport-locked-oversized-type · Studio Freight / Darkroom — Viewport-Locked Oversized Type
Dark Premium
Tiempos Headline / Söhne pairing: old-money serif for claims, neutral grotesque for evidence. Finance gravitas without cliché.
18-endex · Endex
The upper-left brand lockup uses serif type, while each book retains its own cover typography. Keep the interface restrained when the collection already contains many visual voices.
109-stripe-press-a-catalogue-composed-from-book-spines · Stripe Press — a catalogue composed from book spines · model draft
Kinetic Typography / Viewport Stretcher
Tiny 12px uppercase monospace index coordinates (`[01 // ARCHITECTURE]`) sit pinned at the exact mathematical intersections of the 12-column grid beneath the giant display type.
134-studio-freight-darkroom-viewport-locked-oversized-type · Studio Freight / Darkroom — Viewport-Locked Oversized Type
Dark Premium
Hairline borders at 8% white opacity define all structure; no shadows anywhere in dark mode.
16-linear · Linear
The captured catalogue centers a vertical stack of book spines on a dark field, with generous space around the stack. The physical objects become the organizing structure rather than sitting inside a conventional product-card grid.
109-stripe-press-a-catalogue-composed-from-book-spines · Stripe Press — a catalogue composed from book spines · model draft
Kinetic Typography / Viewport Stretcher
No recorded color notes in this slice.
Dark Premium
Purple accent appears ONLY in glows and gradients, never as flat fill — light, not paint.
16-linear · Linear
Most of the visible color belongs to the book spines against the dark background. Let the objects supply variety while the surrounding interface stays quiet; this observation does not establish keyboard or motion behavior.
109-stripe-press-a-catalogue-composed-from-book-spines · Stripe Press — a catalogue composed from book spines · model draft
Kinetic Typography / Viewport Stretcher
Phase-offset sine wave staggering (`delay: calc(var(--line-index) * 45ms)`) turns static multi-line stacked display type into a rhythmic mechanical cylinder.
133-dia-studio-kinetic-variable-type-identity-system · DIA Studio — Kinetic Variable Type Identity System
Project list rows apply a transient `transform: skewX(calc(var(--scroll-velocity) * -0.18deg))` that snaps back to 0deg with a 280ms cubic-bezier ease the instant scrolling stops.
135-locomotive-montreal-scroll-driven-velocity-skew · Locomotive Montreal — Scroll-Driven Velocity Skew
Dark Premium
Feature cards tilt ≤2° on hover with a 400ms ease — motion you sense rather than watch.
16-linear · Linear
Kinetic Typography / Viewport Stretcher
Hovering a full-width project row expands an inline video reel inside the word gap between the client name and the year (`LOCOMOTIVE [REEL] 2026`), pushing the text apart horizontally.
135-locomotive-montreal-scroll-driven-velocity-skew · Locomotive Montreal — Scroll-Driven Velocity Skew
Live waveform bars and countdown timers stay continuously mounted during container expansion, scaling their layout bounds without unmounting or resetting animation frames.
136-apple-dynamic-island-fluid-svg-path-interpolation · Apple Dynamic Island — Fluid SVG Path Interpolation
Dark Premium
Pricing table where the free tier is visually equal to paid — confidence signaling that converts better than dark-patterning.
17-raycast · Raycast
There is no global monthly/yearly switch: a "Billed yearly" toggle appears only in the Basic and Business columns, while the same row reads "Free for everyone" under Free and "Annual billing only" under Enterprise. Steal the per-plan billing row, which places a toggle only where it changes a price and uses the slot to state terms everywhere else.
81-linear-pricing · Linear — pricing · model draft
Kinetic Typography / Viewport Stretcher
No recorded texture/material notes in this slice.
Dark Premium
Subtle noise grain over every gradient stops the banding AND adds materiality at 2% opacity.
17-raycast · Raycast
The right half holds a single 3D cube of near-black facets in mixed finishes (matte, perforated, speckled), lit from above, with one pale light band sweeping diagonally across the lower third of the black ground. Steal one monochrome rendered object as the hero image, giving depth without adding a color.

Diagnostic Findings (6)
- ✗ Violation · Structural GeometryRef #135 ↗
Detected oversized border-radius (`rounded-xl`/`2xl`/`3xl` or >=12px radius) that softens structural grid cells into generic SaaS bubbles.
→ Replace rounded card wrappers with `rounded-none` (`0px`) and exposed `1px solid` hairline borders aligned to Kinetic Typography / Viewport Stretcher.
- ✗ Violation · Surface ElevationRef #135 ↗
Detected heavy drop-shadow (`shadow-lg`/`xl`/`2xl` or blurred `box-shadow`) simulating floating cards instead of tonal surface steps.
→ Remove drop shadows (`shadow-none`) and separate elevation through `--surface-ground` vs. `--surface-elevated` plus `1px` borders.
- ✗ Violation · Chromatic PolarityRef #133 ↗
Detected generic AI-slop indigo/purple/pink gradient classes unrelated to the family's captured chromatography.
→ Strip synthetic gradients and bind surfaces to Kinetic Typography / Viewport Stretcher verified tokens (`#000000` on `#ffffff` (21:1)).
- ✗ Violation · Typographic HierarchyRef #133 ↗
Detected sub-13px micro-copy (`text-xs` or `10px–12px`), which degrades legibility and breaks archival hierarchy.
→ Raise small metadata to `text-[0.8125rem]` (13px) and differentiate with `font-mono uppercase tracking-[0.12em]`.
- △ Warning · Numeric DisciplineRef #133 ↗
Detected numeric figures, prices, or metrics without `tabular-nums` (`font-variant-numeric: tabular-nums`).
→ Add `tabular-nums` (or `.tnum`) so numerals align vertically across rows and live updates.
- △ Warning · Interactive ErgonomicsRef #135 ↗
Interactive element (`<button>`, `<a>`, `<select>`) lacks an explicit >=44px (`min-h-11`) touch/click target.
→ Add `min-h-11 inline-flex items-center` to interactive controls.

How Trova compares to other design reference platforms
Visual galleries (Godly, SiteInspire, Refero), product screen trees (Mobbin, Page Flows), typographic archives (Fonts In Use), and associative graphs (Are.na) each solve one slice of research. Trova is built around the missing link between seeing a reference and shipping an interface: named, testable steal-notes (447 notes across 201 references and 12 multi-step flows), verified open-source font stand-ins, measured WCAG contrast pairs, and a 6-tool MCP server for AI coding agents.
