kit

Reusable plain-CSS/HTML building blocks that recreate the RoboCo control panel's look, for compositions that want to simulate the product rather than run a text card. Hand-rolled (no React, no Tailwind, no bundler) — this is a recreation of the panel's design language, not a port of its components. Load kit.css (and kit.js if you use the typing helper); no composition-level theme.css is needed, kit.css owns the reset + fonts.

<link rel="stylesheet" href="../../kit/kit.css" />
<script src="props.js"></script>
<script src="../../kit/kit.js"></script>

Every class is namespaced pk-. See compositions/panel-demo/ for a full worked example (task types in, a card appears, a cursor clicks it done, a toast confirms it).

Pieces

• pk-frame — the app chrome: a slim sidebar (pk-frame__sidebar, pk-frame__navitem[--active]) and a top bar (pk-frame__topbar, pk-frame__search, pk-frame__status for the pulsing "Live" dot) around a pk-frame__content area. Fixed sidebar/topbar sizing works at both 1080x1920 and 1080x1080 — only the content area's height changes.
• pk-column / pk-card — a kanban-ish list container (pk-column__header + children) hosting task cards. A card is pk-card__title, pk-card__meta (chips + pk-card__assignee), and pk-card__status (a pill).
• pk-chip — a small team/priority tag: <span class="pk-chip pk-chip--purple">Frontend</span>. Variants: --purple, --blue, --green, --orange, --pink, --gray.
• pk-pill — a status pill: <span class="pk-pill pk-pill--progress">in progress</span>. Variants: --progress, --review, --approved, --completed. To swap one pill for another (e.g. progress -> completed), stack two pills at the same spot inside a position: relative pk-card__status and give the outgoing one pk-pill--swap-out (fades in then out) and the incoming one pk-pill--swap-in (fades in and stays), each with its own --pk-pill-enter-delay / --pk-pill-exit-delay (composition-absolute seconds — the same convention data-start uses).
• pk-toast — a notification card that slides in from a corner: pk-toast__icon + pk-toast__body (pk-toast__title, pk-toast__text). Position via --pk-toast-bottom (right-anchored).
• pk-type / pk-caret — character-by-character typing reveal. Write the target element's final text directly in the HTML, then call window.PanelKit.typeText(el, { delay, stagger }) (from kit.js) once, synchronously, before rendering starts — it splits the text into pk-type__char spans with staggered animation-delays (works with any font, no per-character width math). delay is the composition-absolute second the first character appears; stagger defaults to 0.045s/char. Add a <span class="pk-caret"></span> next to it for the blinking caret.
• pk-cursor — a small CSS-shape cursor (pk-cursor__glyph) that glides along a straight path and pulses (pk-cursor__ring) on arrival. Position via --pk-cursor-x0/y0/x1/y1 (content-box-relative pixels) and timing via --pk-cursor-delay (glide start) / --pk-click-delay (pulse start), all composition-absolute seconds.

Offline constraints (same as every composition)

No CDN, no npm runtime deps, no bundler — plain files only, loaded via relative paths (../../kit/... from a composition two levels down). Fonts are the vendored motion/public/fonts/*.woff2, loaded via @font-face in kit.css. Motion is CSS keyframes timed with animation-delay (seconds from frame 0 — no requestAnimationFrame, no Date.now()), so a render is frame-deterministic.
