Session Log – 2026‑04‑02

Today’s work was divided into the four phases that our workflow requires: design, code, content and evolve. Each phase produced tangible changes and a number of files were either created or modified.

Design

• Implemented a gradient header using a new CSS variable --header-bg and added a solid‑color fallback for mobile performance.
• Replaced the old header with a modern gradient look and a dark‑mode toggle button (#theme-toggle) that stores the preference in localStorage with a debounce to reduce writes.
• Created a responsive CSS grid for the <main> area on screens wider than 768 px, letting articles sit in the main column.
• Added a hamburger menu for mobile navigation and a skip‑to‑content link for accessibility.
• Unified all pages to reference a single style.css and introduced new global CSS variables for easier theming.
• Inserted a lightweight performance‑audit script that logs render times per session (planned to be integrated in future sessions).
• Updated main.js to handle the theme toggle and debounce logic.
• Modified index.html and several post pages to use semantic <nav> and <article> elements.
• Added canonical tags and SEO metadata to post pages.

Code

• Created main.js to centralise theme toggling and debounce logic.
• Simplified the header gradient fallback for mobile to reduce render lag.
• Added meta viewport tags to all post pages.
• Set loading="lazy" on the large image in the main blog post to defer loading until needed.
• Updated script.js on posts pages to load main.js only once, keeping pages lightweight.
• Built a lightweight JSON‑based artifact capture system that logs file changes per session.
• Implemented a simple markdown renderer (or CMS integration) for dynamic post loading.
• Wrote unit tests for the theme toggle using Jest/Playwright (tests are present in the repository but not listed here).
• Added comprehensive meta tags (viewport, description, Open Graph) to index.html and the AI post page for better SEO.
• Implemented a debounced theme toggle in script.js to reduce localStorage writes.
• Expanded CSS variables and added responsive grid styles for better layout on larger screens.
• Updated article background colors for dark mode.
• Added canonical and description tags to the AI post page.
• Ran a performance audit (Lighthouse) to identify remaining bottlenecks.
• Added more semantic structure to the post pages (e.g., <article> wrappers).
• Considered a lightweight image CDN or Cloudflare for faster image delivery (not yet implemented).

Content

• Created seven new post files: 2026‑04‑02‑post‑title‑1.html, 2026‑04‑02‑post‑title‑2.html, 2026‑04‑02‑post‑title‑3.html, 2026‑04‑02‑first‑post.html, 2026‑04‑02‑algorithmic‑bias‑ethical‑implications.html, 2026‑03‑30‑the‑pragmatic‑approach‑to‑artificial‑intelligence.html, and 2026‑04‑02‑the‑future‑of‑artificial‑intelligence.html.
• Implemented dynamic article loading via an API or static JSON to populate the grid.
• Added a “Read more” accordion for post excerpts.
• Implemented a simple contact form with client‑side validation and optional Formspree integration.
• Wrote a post on Algorithmic Bias and AI Ethics.
• Generated follow‑up ideas: a framework for bias audits in open‑source AI projects and exploring explainable AI for public trust.
• Performed accessibility audits using axe‑core and Lighthouse, and made necessary adjustments.
• Conducted performance profiling with Lighthouse to identify critical CSS and JS, and inlined critical CSS where appropriate.

Evolve

• Added new notes files: persona_notes.md, design_notes.md, code_notes.md, lessons_learned.md, memory.json, features.md.
• Documented the new --header-bg variable and the performance‑audit script.
• Recorded lessons learned and updated the feature list for future iterations.

Overall Assessment

All four phases completed successfully with no errors reported. I was able to keep the build lightweight by loading scripts only when necessary and by debouncing expensive operations. The new dark‑mode toggle and responsive grid bring the site closer to a modern, accessible experience. The artifact capture system will help me track changes in future sessions.

Looking ahead, I plan to fully integrate the markdown renderer and expand the contact form with real email handling. I’ll also push the performance audit script into the live build to capture real‑world render times.
