The parts.
The whole system.
The visual language of juansync.dev, from a single teal signal to the pages built around it. Explore the patterns, try the components, take the code.

Near-black. Cool ink.
One teal signal.
One teal signal.
// 01 · overview
One site. Several kinds of page.
A shared night shell connects the site. The content determines how much space, detail and motion belongs inside it.
Writing ↗
Featured pages, filterable post cards and the lesson log.
View page source →Learn ↗
Night index; article bodies follow the reader’s light or dark preference.
View page source →Trackers ↗
Shared tracker navigation, a left version rail and centered release detail.
View page source →Lab ↗
Seeded figure templates and an exportable hardware icon kit.
View page source →Anatomy ↗
Step controls and selectable parts beside an explanatory figure.

Use --nt-* for current pages, NightPage for the shell, and shared components for repeated patterns. The lime, typewriter and lofi library remains available below for older sections.
// 02 · foundations
Colour has a job.
Grounds recede, ink stays readable, teal marks an action or a point of attention. Hairlines separate content without turning every section into a filled card.
Each swatch copies its CSS variable. Values and token lists come directly from the production token files at build time.

The work keeps its meaning.
Readable prose carries the explanation. Headings stay brighter and stronger; comments stay quieter without disappearing.
// November 2026 · a concise public overview
New presentation pages use distinct title, body and comment roles. Background contrast and separation between roles are checked by the presentation contract. A quiet comment still has readable contrast; a gradient does not carry essential text.

The reading page
Night chrome around a restrained article. Learn bodies become cream paper for light-mode readers; dark-mode readers keep the night ground. Code stays in a dark terminal in both.
Night / dark preference
Evidence before confidence.
Readable prose, quiet lines and a single highlight.
Paper / light preference
Evidence before confidence.
The same hierarchy, on warm paper with darker ink.

<h1>Inside a chip package</h1>

The part of a chip you never see. Step down through the package of a phone's processor: one die, no lid, and its
memory stacked right on top. Use the arrows, a number key, or pick a part.

<h2>An accelerator, opened</h2>
<p>
A phone stacks its memory on top of the processor and reaches it through a ring of a few hundred balls. The largest
AI chips need thousands of memory wires, so their memory sits beside the compute dies on one slab of silicon: two
dies joined edge to edge, eight memory stacks along their sides. Click it to close it or open it again, or point at
a part.

<span class="label">// one stack, cut open</span>
<h2>Inside a memory stack</h2>
<p>
Each of those eight stacks is a tower of its own: a logic die at the bottom, eight DRAM dies above it, and no wire
bonds or package balls anywhere. The phone's memory wires each die from its edge; a stack this wide has to wire
straight down through the middle of every die. Here one stack is cut along a row of those vias and lifted apart.

Every logic die here is built in three stages. The front end makes the transistors, in the top hundred nanometres
of the wafer; the middle of the line makes the contacts that reach down to them; the back end stacks the wiring
over them, fifteen to twenty levels of copper on a leading chip, each turned a right angle from the one below and
coarser than it. Here a block a few gates wide is cut open on two faces and lifted apart. The heights are
stretched: the transistors are about a hundred nanometres tall, the wiring over them about ten micrometres. Click
it to close it or open it again, or point at a layer.

The presentation page
Lead with an outcome, a clear promise and a useful next step. Keep the landing page at a high level; move architecture, definitions, examples and checks into linked guides.
// the experience vault
Keep the useful part.
One small introduction; deeper context when a question needs it.

ScrollTrigger coordinates drawer travel, masked heading words and guide cards. Motion marks section continuity; reduced motion and a missing script keep all copy readable.
