The black hole is solved, not drawn.

The shape behind the home page isn't an image or a lens flare. For every pixel on the screen, a light ray is traced backward through curved spacetime by integrating the Schwarzschild null-geodesic equation — d²u/dφ² + u = 1.5 r_su², where u is inverse radius — with fourth-order Runge-Kutta, taking finer steps where the curvature is steepest.

Everything strange about the picture falls out of that one equation rather than being drawn in by hand.

• The haloYou are seeing the far side of the diskLight from behind the hole bends over the top and under the bottom before reaching you, so a flat disk appears to arch above its own shadow.
• AsymmetryRelativistic Doppler beamingGas orbits at a large fraction of light speed. The side turning toward you is boosted and blue-shifted; the receding side is dimmed. Intensity scales as the fourth power of the Doppler factor, which is why one side is dramatically brighter.
• ColorTemperature, plus the climb outA thin accretion disk runs T ∝ r^−3/4, so the inner edge is blue-white and the rim cools to orange. Light also loses energy escaping the gravity well, reddening as it goes.
• EdgesReal radii, not chosen onesThe disk stops at the innermost stable circular orbit, three Schwarzschild radii out, because no stable orbit exists closer. The shadow is wider than the horizon itself — light passing within about 2.6 radii cannot escape.
• JetsCollimated outflow along the spin axisAccumulated volumetrically as the ray passes through them, and beamed by the same relativity as the disk — which is why they brighten as the viewing angle tilts on scroll.
• The fallScrolling is descendingThe page is four full screens, and the camera is released from rest at the top. Its speed at each depth is the exact free-fall value for a body dropped from that starting radius, so the approach accelerates the way gravity actually accelerates rather than on a linear ramp.
• AberrationFalling makes the shadow smallerThe counterintuitive one. Because we are moving, the direction a pixel looks is not the direction that light travelled, so every ray is transformed between frames before it is traced. Our own speed sweeps extra sky into the forward view — which means an infalling observer measures a smaller shadow than someone hovering at the same radius, and light met head-on arrives blueshifted and brighter.

Everything you see out the window is math.

The presentation is set inside Haven-1, looking out the domed window. There are no photographs and no downloaded textures anywhere in that scene — the planet, its cloud deck, the atmospheric rim, and the stars are all generated in the browser at load time.

• EarthDrawn to a canvas, wrapped to a sphereOcean gradients, weather bands, and cyclone swirls composited procedurally, then used as a texture. Because it's a sphere map, the rotation loops seamlessly forever.
• AtmosphereA custom GLSL shaderThe blue rim is a fragment shader computing light falloff against the surface normal — not a glow image pasted over the edge.
• StarsA particle system that twinklesEach star carries its own phase offset, so a vertex shader can vary brightness independently across thousands of points in a single draw call.
• ScrollWalking toward the glassScroll position drives the camera and widens the window aperture, eased frame by frame so it glides instead of snapping.

Signed in is not the same as allowed in.

Authentication services let anyone create an account. Checking only whether a visitor is signed in would mean anyone who signed themselves up could read a private presentation — so the portal checks the account's email against an explicit allowlist, on the server, in the layout that wraps every page beneath it.

Guessing a URL doesn't help: the check runs before any content is rendered, so unlisted accounts receive a polite door rather than a page. A second, narrower list governs the pages meant only for me.

What isn't here, on purpose.

A dependency you don't add is a dependency you never have to upgrade, audit, or explain. Everything below was considered and left out.

• No CSS frameworkNo Tailwind, no component library. One global stylesheet and a single CSS module. The whole visual system is a handful of custom properties.
• No webfontsSystem font stack. Nothing to download, nothing to block the first paint, no third party watching who reads the page.
• No imagesNot one raster file anywhere. Every visual is geometry, shader, or text — even the brand marks above are SVG paths written into the page, so nothing is fetched.
• No analyticsNo trackers, no session recording, no cookie banner to dismiss — because there is nothing to consent to.
• No CMSContent lives in typed components in version control. A wrong word is a diff, and every revision has an author and a timestamp.

The PowerPoint is generated, not drawn.

A live site is a single point of failure in a conference room, so there is a PowerPoint fallback — but nobody dragged those text boxes by hand. A Node script composes the deck with pptxgenjs, laying out every slide from the same content the site renders and writing each spoken beat into the speaker-notes pane.

Which means a wording change is one edit and one command, not thirty slides of find-and-replace — and the file and the website cannot quietly drift apart.
