UI Components Easy
Science — Author + Affiliation + ORCID
A scholarly author byline block in the institutional house style — names carry superscript affiliation numbers, equal-contribution daggers, a corresponding-author asterisk, and a green ORCID iD that opens orcid.org. Hovering or focusing any author lights up their matching numbered affiliations, and hovering an affiliation row highlights every author who belongs to it. The corresponding-author asterisk reveals a copyable email popover, and a segmented control switches between an expanded byline and a compact single-line variant.

<h2>Abstract</h2>
<p>We present a probabilistic framework that jointly inverts long-wavelength
geoid anomalies and present-day plate velocities to recover the radial
viscosity structure of the mantle. Using a Markov-chain Monte Carlo sampler
across <span class="mono">2.4 × 10⁶</span> forward evaluations, we constrain the
lower-mantle viscosity to <span class="mono">(1.8 ± 0.3) × 10²² Pa·s</span>,
a factor of <span class="mono">38±6</span> above the upper mantle. The recovered
profile is robust to lateral temperature heterogeneity below
<span class="mono">660 km</span> depth.</p>
<p class="kw"><strong>Keywords:</strong> mantle viscosity · geoid inversion · plate kinematics · Bayesian inference</p>

</html>Author + Affiliation + ORCID
A complete journal-style byline rendered in the institutional house style — Inter for the author names and chrome, Source Serif 4 for the abstract prose, and JetBrains Mono for the DOI, dates, and figures. Each author name carries superscript affiliation numbers, a teal dagger for equal contribution, a red asterisk for corresponding authors, and a small green ORCID iD that links out to orcid.org in a new tab. Below the names sits a numbered affiliations card and a legend explaining every mark.
The block is wired for fast scanning. Hovering or keyboard-focusing an author highlights exactly the affiliations they are attached to, with an accent rule down the side of each matching row; conversely, hovering an affiliation row lights up every author who belongs to it. Clicking the corresponding-author asterisk reveals a small dark popover with a mailto: link and a Copy button, dismissible by clicking away or pressing Escape, and confirmed with a transient toast.
A segmented radiogroup toggles between two presentations: an expanded byline with the full affiliations list and legend, and a compact variant that collapses everything to a single muted institution line beneath the names — the pattern used for dense reference lists and search results. The control is arrow-key navigable, the layout reflows cleanly to ~360px, and reduced-motion preferences are honoured.
Illustrative UI only — fictional authors, data, and figures; not real scientific results.
