Round 2 iterates the two winners (swiss studio, three systems) with the salmon logo system woven in: the integral glyph from the "of", the heritage wordmark as provenance, methods in the prose instead of lists. Round 1 kept below for reference.

the four pages behind the landing dots, rebuilt as swiss-studio siblings.
Existing copy ported faithfully (15 years kept, em dashes removed), shared css/swiss.css, filenames preserved so the landing page's dot links keep working. Nav echoes the landing mechanism: four dots, current page filled in accent blue. No JavaScript.

Option 2's grid with the blue swapped entirely for logo salmon. The integral monogram works at four scales: a full-height glyph closing the hero wordmark, a nav ligature, a marker beside each numbered section, and a caption mark on a Stan model fragment set like a pull quote ("beliefs, written down before the data arrives"). Heritage wordmark small in the footer as provenance.

The textbook take: black and white with salmon reserved for the integral glyphs. Nine margin notes annotate the prose like a well-thumbed statistics text ("posterior proportional to prior times likelihood", "the DAG is the contract"), each tied to its paragraph with a salmon tick. The integral does its literal day job inside a labeled Bayes identity. Notes fold inline on mobile.

Option 5's warm-paper narrative recast as a field notebook. Each chapter opens with the rotated circular stamp monogram in uneven ink; diagrams keep their hand-drawn strokes with the key node turned salmon; captions carry the methods ("the DAG, specified before the data"; "posterior over dose response, drawn from NumPyro"). Integral ornaments divide the chapters.
three systems, one thread.
The whole page is a single integral sign: a 3px salmon thread opens as the glyph's tail beside the hero, descends a left rail through a roman-numeral station at each chapter, branches into each diagram, and closes its bottom hook beside the heritage wordmark in the footer. A large Bayes formula gets its three terms underlined and labeled posterior, likelihood, prior. Below 700px the thread degrades to per-chapter segments.

A dark phosphor-green terminal where the hero is a framed shell session and every section renders as command output: a pillar grid, project cards with box-drawing stat lines, key-value whoami, and CTA buttons. Fixed nav is a row of fake flags with scroll-aware highlighting; subtle scanline and vignette overlays sit over an AA-contrast palette, and reduced-motion users get a fully static page.

White ground, near-black ink, one accent blue, a huge lowercase serif wordmark with a blue period, and a strict 12-column grid with thin rules and numbered pillars. Selected work renders as three editorial grid rows with mono metadata and real fact-sheet numbers, closing with credentials, an arrow-hover contact list, and the "matrices . earth" footer.

Warm white, ink, and deep teal, centered on three interactive proof-of-skill widgets: a Bayesian coin-flip posterior with a live credible-interval readout, a momentum optimizer descending a teal contour valley, and an SVG pipeline that diverts uncertain cases to human review. Full copy ships for all four pillars, three work items, credentials, and contact, with no-JS fallbacks and reduced-motion handling.
matrices / systems that decide.
Oversized black display type on a faint grid, hard 2px borders with offset black shadows, and a single red accent used only where it stays WCAG AA. A four-pillar marquee strip, rotated work cards that straighten on hover, key-style buttons that depress on press, and an inverted black footer, all readable with JS disabled and responsive to 360px.

An essay-style scroll on warm paper with a serif stack: three chapters (serif, prism, markets), each written as problem, approach, result, with sticky roman-numeral chapter labels and a hand-drawn inline SVG figure per chapter. Closes with the four pillars as a compact index, credentials, a contact block with a calendly button, and the "matrices . earth" footer.
