@habemus-papadum/aiui-slides

A slides framework for aiui apps: a deck of viewport-sized slides where the current frame is a pair of controls — durable, deep-linkable, and drivable by keyboard, widget, wheel, touch, URL, or agent ("next", by voice, through the derived tools).

• Slides are data — a deck is an ordered SlideDef[] (id, title, content, optional preview and steps); the URL segments, HUD grid, and nav all derive from the array.
• Scenes — a slide with steps: n plays n additive scenes inside itself before the deck moves on: components stay mounted and share the slide's reactive graph, a scene is a CSS state flip on useSlide().step() (the Step helper cans the idiom), and backing up un-plays them one by one.
• Every input means one frame. Wheel and touch are interpreted, not native: pure intent machines quantize a flick (inertia tail and all), a wheel notch, or one finger-down into exactly one step — the next scene, or the next slide once the scenes are spent. Keys, the cue, the dots, and the agent verbs dispatch the same unit.
• createDeckModel(scope, slides) declares the slide + step controls and the next/prev actions under your app's scope — one toolkit serves navigation and content.
• <Deck model={deck} basePath={deckBase("slug")} /> renders the translated track (CSS glide between slides) and the chrome: the one-step cue (immediate on the title frame, back after 10 s of rest, flipping up at the very end), scene-position dots, nav widget, HUD overview grid (every slide's cheap pure preview at a glance — slide-grained, like the URL), modal-kit keymap, and slide ↔ URL binding (replaceState; slide 0 is the bare base).
• Lens — levels of detail for any page: inline trigger → hover peek → interactive detail overlay, folded into the page's own reactive graph.
• useSlide() — a slide's handle (index, deck, active(), step()); gate rAF loops on active() so off-screen slides park themselves.

Default styling is the opt-in stylesheet — retheme via the --aiui-deck-* / --aiui-lens-* tokens or ship your own sheet against the same class names:

import "@habemus-papadum/aiui-slides/styles.css";

The reference deck is demos/gear-talk (the involute gear as a six-slide talk); the decided design contract is docs/proposals/slides.md in the pdum_aiui repo.
