Introduces an isolated interactive Northern Lights canvas laboratory experiment at src/pages/lab/aurora.astro powered by native sine wave superposition, vector magnetosphere displacement, and light refraction utilities (src/utils/aurora-math.ts). Fully verified with Vitest tests, Playwright visual testing, and Astro type checking.

Summary by CodeRabbit

  • New Features

    • Added an interactive Northern Lights Lab with animated aurora visuals.
    • Added controls to pause or resume animation, adjust wave speed, and change refraction density.
    • Added pointer-responsive magnetic-field effects and support for reduced-motion preferences.
    • Added responsive behavior for touch devices and mobile viewports.
  • Tests

    • Expanded coverage for aurora calculations, color transitions, validation, and analytics behavior.
  • Refactor

    • Improved compatibility and type safety without changing visible behavior.

📝 Walkthrough

Walkthrough

The change adds a Northern Lights lab page with an interactive canvas simulation, reusable aurora math utilities, and tests. It also adds ambient runtime declarations and updates several existing types, tests, and DOM calls.

Changes

Aurora Lab

Layer / File(s) Summary
Aurora math utilities and tests
src/utils/aurora-math.ts, src/utils/aurora-math.test.ts
Adds typed wave, displacement, color interpolation, and RGBA formatting utilities with boundary and representative test coverage.
Interactive aurora page
src/pages/lab/aurora.astro, .jules/prism.md
Adds the accessible canvas lab, animation controls, pointer interaction, reduced-motion handling, responsive styles, and Astro teardown logic. The journal records the implementation details.

TypeScript and Test Alignment

Layer / File(s) Summary
Ambient runtime and DOM declarations
src/env.d.ts
Adds NodeJS globals, Buffer, filesystem signatures, module declarations, and the Element.append declaration.
Test and configuration type fixes
__tests__/release.spec.ts, src/__tests__/content.config.test.ts, astro.config.mjs
Adds explicit mock types, guards schema validation calls and results, and documents the Codecov plugin compatibility cast.
Existing browser API and schema type alignment
src/utils/github-releases.ts, src/components/Chat.astro, src/components/Footer.astro, src/utils/hire-analytics.test.ts
Updates Zod issue typing, narrows the chat root type, uses explicit DOM operations and boolean coercion, and assigns an undefined analytics data layer directly.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Same Prism Northern Lights /lab canvas farm as #758 / #739 / #725 / #709 / #682 / #670 / #659 / #649 / #609: src/pages/lab/aurora.astro + aurora-math + .jules/prism.md, plus the usual type-guard / env.d.ts / Footer no-ops.

Not hire-path. Isolated lab page does not belong on the visitor branding site.

No Prism onto main. Do not reopen as Jules. No freeze. No kernel to park.

Copy review (Eden): new visitor-facing page at /lab/aurora. No flag gate, no noindex — once merged this is a real public URL, not a tucked experiment.

Hero/meta copy is physics-paper soup again ("sine wave superposition", "vector magnetosphere field"). Title pattern doesn't match the rest of the site. No LinkedIn hire CTA.

Same class as #758 / #739 / #725 / #609. Locked: no Prism onto main — not hire-path. Reading list is the bar for copy if this ever ships as a visitor page. Inline notes have replacement lines. Hold on the writing; Nick/Bob usually close this farm unmerged.

(Can't request-changes on your own PR via this login — treat this as a hold on the copy.)

.jules/prism.md journal is out of scope for me; Bob/Dan usually strip those before merge.

Page chrome is the first second a visitor gets. "math-driven aurora refraction and vector magnetosphere field" / "sine wave superposition" is lab-notebook speak, not visitor copy — same trap as #758 and the tech-stack PR.

Also match the site title pattern (… | Product Manager, Developer Experience at IFS), not | Alexander Härenstam Lab.

Suggest:

  • title="Northern Lights lab | Product Manager, Developer Experience at IFS"
  • description="Move your pointer through an aurora canvas. Waves bend around it."
  • Hero title: Northern Lights lab
  • tagline: Move your pointer through the aurora. The waves bend around it.

Updated page title to Northern Lights lab | Product Manager, Developer Experience at IFS, description to Move your pointer through an aurora canvas. Waves bend around it., Hero title to Northern Lights lab, and Hero tagline to Move your pointer through the aurora. The waves bend around it. to align with site branding patterns.

Missing the hire path. Reading list (and every visitor page that should convert) ends with LinkedIn: Get in touch + LinkedIn · replies from me. A public /lab/aurora page with no CTA is a dead end for the brand lock (LinkedIn only, no email).

Add the same CallToAction block reading list uses, under the canvas section.

Stiff for on-canvas help. Prefer something a person would say:
Move your pointer — the aurora bends around it.

(Also: "Refraction Density" on the slider below is physics chrome. Layers or Detail reads cleaner for a visitor.)
