Merging this deploys to stratalab.cc, so it waits for Bharat's go-ahead.

The mascot

An original little Palaeolithic digger, drawn as inline SVG to look like a coloured-pencil sketch: ink outlines over fills printed slightly off register, with a slow "boil" on the lines. He wears a fur tunic and a malachite-bead necklace, and carries a flint pick. All movement is CSS, and it stops under prefers-reduced-motion.

Where	What he does
Landing, on top of the core	Chips at the surface every few seconds and throws up grit. He waves when you hover over him; tap him and he hops and the core shakes.
Footer, every page	Walks along the sediment rule and turns around at each end.
404	Scratches his head next to the empty core.
Upload box	Waves on hover and cheers while you drag a file over the box.

Clearer clickables

• How it works (Upload / Place / Fit / Test): each step is now a bordered, raised key with a chevron. It lifts on hover and sinks when pressed, and the chosen step gets a malachite outline. The step's action ("Upload a file →") is a button, and "Play again" has an icon.
• How it is built: a "Tap a box to see what it does." hint with a tapping hand, a ⊕ badge on every box (a filled ✓ on the open one), and a halo that glows over the boxes in turn until someone points at one.
• Upload: the whole drop zone opens the file picker, not just the small link. It now has hover, keyboard-focus and drag states, plus a "Choose a file" button. Drag-leave no longer flickers when you pass over the zone's own contents.
• Site-wide: buttons, tabs, label[for] and summary get a pointer cursor, because Tailwind v4's reset gives buttons the arrow. Under reduced motion, looping animations now run once and stop; before, they flickered through their frames.

Screenshots

Checks

• pnpm typecheck, pnpm test (53 passing) and pnpm build all pass.
• Screenshots come from the static build against a local API at 1280px and 390px.
• With reduced motion emulated, no mascot animation runs.
