Interval: shamseddin.net

Read README.md and docs/DIRECTION.md before changing the site.

The site should feel like an instrument rather than a brochure. Its argument is AI for science and
science for humanity's good, demonstrated across fields. Provenance and uncertainty remain a working
discipline, not the headline.

Current page model

• index.html: Home, including the unique CV material.
• projects.html: a bounded, interactive viewer for Bowcast and Black Hole Census.
• about.html: biography and working principles.
• GitHub remains an external navigation item.
• There is no separate cv.html.

Non-negotiables

• Never show a number without its source or epistemic status.
• Rows never share a scale.
• No em dashes and no emoji.
• No cards, rounded containers, shadows, decorative gradients, backdrop blur, or sticky elements.
• Use only the two real project marks in the Projects selector. Do not add decorative icons.
• Self-host the portfolio fonts.
• Colour carries meaning or it does not appear.
• Give every page at least 120px of bottom padding.

Motion override

On 2026-07-28 the owner explicitly overrode the earlier ban on scroll-triggered reveals.

Use IntersectionObserver, stagger direct children in reading order, and animate only opacity and a
small vertical transform. The content must remain visible when JavaScript is off, when the observer is
unsupported, after the safety timeout, and under prefers-reduced-motion. Do not add parallax,
scroll-jacking, sticky elements, or continuous scroll effects.

Bowcast reading

The Home reading uses the public Bowcast likelihood endpoint for Victoria. Preserve the pre-rendered
no-data state and do nothing on null data, network failure, timeout, or an invalid response. The live
response uses percentage probability, a weighted ensemble estimate, so never label the ticks as a
literal count of agreeing members. locations[].probability is the day's peak interval, not the
value at this moment, so the label must keep naming that window (bestInterval).
