// looking for a date picker does not know, and should not have to guess, whether it was
// filed under forms or under overlays. So: one page, one scroll, and a sidebar of groups
// that jumps you to the one you are after.
//
// The section ids come from componentGroups.ts, which is also what the sidebar renders —
// so the sidebar cannot offer a jump to a section that does not exist.

Components
Every component in the Solid kit, running. Not a screenshot of one anywhere: each block
below is the real component, imported from @ui/* and rendered
on this page. Use the sidebar to jump to a group.
They are ordinary Solid components: named exports, props in, an element out. Two things
catch people out. Handlers keep their DOM names —{" "}
onclick, oninput,{" "}
onchange, never onClick. And
many props accept a signal getter as well as a value, so you can pass{" "}
value={"{"}name{"}"} rather than{" "}
value={"{"}name(){"}"} and let the component track it.

A badge is a solid fill with white text, so it stays legible in both themes without a variant
on it. An alert is the opposite: a wash of colour behind dark text, which is exactly the case
a token cannot carry into dark mode — a red-50 tint is invisible on a near-black surface — so
alerts are one of only two places in the kit with a dark: rule.
active
failed
info
pending
default
muted
An informational message with a header.
A success alert, with no header.
Something needs your attention.
Something went wrong.
And a neutral one.
On the plain surface.
{/* It is absolutely positioned (top-0 -right-2), so it needs a relative
ancestor to hang off — normally the logo. And it renders NOTHING in

FontAwesome, tree-shaken. The bundler scans the source for the names actually referenced,
pulls just those paths out of the SVG kit, and emits a registry containing only them —
which is why this site ships a few dozen glyphs rather than FontAwesome's 41.5 MB kit.
A name nothing in the source references is not bundled; a name the kit has never heard of
renders an empty box and is reported by the bundler rather than shipping silently.
IconContainer
IconInline sits on the text baseline
The last two are the same name in the solid and regular styles. Which one you get by
default is a CSS variable the app sets, read at runtime.

Click a Qty or Price cell and type; Tab and the arrow keys move between editable cells.
The grid does not own the rows — it tells you which cell changed and hands the value back.
AutoTable is the big one. Sort by clicking a header, drag a header to reorder it, use the
toolbar to hide a column or export what you are looking at. The column layout is keyed to
localStorage, so it survives a reload.

Tooltips, popovers, menus and modals — every one measured against the real viewport. A
floating panel portals itself to document.body, positions from
its trigger's bounding box, and flips or shifts when it would otherwise run off the screen.
None of them needs a host or a portal root mounted anywhere. That is the difference from a
modal library that makes you remember a <div id="portal">{" "}
at the bottom of your index.html.
Top
Right
Instant
A tooltip that only answers to a mouse is a tooltip a keyboard user cannot read.
Click me
Click outside, or press Escape. Only the TOPMOST floating panel closes per press.
Aligned to my right edge
Placement bottom-end.
Hover, then reach the panel
Move the cursor across the gap and onto this panel — it stays open. Select this
text to prove it. Without that grace period the panel would close in the dead
space between the two, which is what happens once a panel is portaled and CSS
:hover no longer reaches it.
The items raise toasts, which is how you can see that an item really does close its own
menu — and that the one marked closeOnClick={"{false}"} does not.
setModalOpen(true)}>Open modal
setConfirmOpen(true)}>
Delete something…
setWizardOpen(true)}>
Open wizard
Open the modal, then the nested one inside it, and press Escape twice: modals unwind ONE
LAYER per press rather than all at once.
setModalOpen(false)}
header={A modal

footer={
setModalOpen(false)}>Close

Take the tour
It dims the page, cuts a hole around each target, and animates the spotlight from one
to the next. Targets are CSS SELECTORS — the same section ids the sidebar jumps to.

The scorer is headless too: rankFuzzyMatches and{" "}
fuzzySegments give you the ranking and the highlight runs,
and you render them however you like.
Pass andAmpersand and the word "and" and the symbol "&"
match each other, so "First Bank and Trust" also finds "First Bank & Trust". The exact
spelling still wins — the substituted form is a penalized extra pass, not a free swap — and a
stray "and" inside "Standard" or "Brand" is left alone.

change series and Solid re-renders the marks that moved. There is
no update() to call.
Being SVG buys two things a canvas cannot. The marks name the theme tokens
(var(--color-chart-1) …), so the palette inverts for dark mode with
the rest of the site — a canvas paints pixels and cannot read a CSS variable. And every mark is a
real element, so hovering shows a crosshair and one tooltip listing every series at that point.

Each chart carries a title; a multi-series chart also draws a
legend. Click a legend key — say Errors or a donut slice — to hide it, and the scale
and marks recompute from what's left. The threeD prop gives
every plot a 3D grid — bars extrude, a line or area draws flat over it, the donut tilts.
The same depth and tilt give the grid
itself perspective: a floor recedes from the value-0 baseline into a back wall. Bars extrude into
that space; a line or area stays flat on the front plane, drawn over the grid and read against the
front axis — the stroke is not itself extruded, since depth on a hairline reads as noise.{" "}
tilt runs 1 (head-on, near-flat) to 0 (bird's-eye);{" "}
depth is the sweep length in px.

from the container, so a chart fills whatever column you give it.

stacked layers the series with a 2px surface gap between segments.

The swatch class is written out in full in the source, not built as{" "}
"bg-" + name. Tailwind finds the classes it must compile by
scanning the source for literal strings — a concatenation is invisible to it, and every
swatch here would come out colourless.
Coloured tints
A red-50 wash is invisible on a near-black surface. An
alert's tint has to become a deep, transparent one — a different colour, not a
different value of the same one. One of only two places a{" "}
dark: variant survives.
Fills that invert
The neutral button is dark on a light page and light on a dark one, so its label must
invert with it — text-white would disappear the moment
the fill went pale. Hence three tokens, not one. The other place.
