Changelog

Complete site redesign — moved from a dashboard-oriented sidebar layout to a content-first design with a horizontal top navigation bar

Mintlify-style mega menu: "Learn" dropdown (2×2 grid: Lessons, Grammar, Quizzes, Progress), "Blog" dropdown (categories + lazy-loaded latest posts), "About" simple dropdown

Responsive mobile drawer menu with accordion-style expandable sections for Learn, Blog, and About

Homepage completely rewritten as a proper landing page (hero, stats strip, 3-column features, how-it-works steps, latest blog posts, FAQ, final CTA) — no longer a personal dashboard

FAQPage schema on the homepage for Google rich result eligibility

Footer redesigned as a 3-column layout: brand + CC0 license, Learn links, Company links

Left sidebar and bottom mobile nav replaced by the new top navigation bar

Editor's Picks / highlighted posts system — tick the "Highlight this post" checkbox in the CMS to feature a post in a dedicated section on the blog page and below the TOC on every single post

Google AdSense auto ads scoped to blog pages only (/blog and /blog/*) — homepage, lessons, grammar, and quizzes are ad-free

ads.txt file at /ads.txt for Google AdSense publisher verification

Blog list page container widened to max-w-5xl for a more spacious editorial feel

Blog list page and filtered/paginated view now have sticky left and right ad sidebars (w-[160px], visible at 2xl breakpoint) — fully managed via /polaris/ads using slot keys blog-sidebar-left and blog-sidebar-right

Blog sidebar ads positioned at 25vh offset and sticky at 30vh so they appear in the mid-screen zone rather than pinned to the top edge

Single post layout changed to 3-column: left sticky ad sidebar (post-sidebar slot) | centered max-w-2xl article | right TOC

Single post TOC and left ad sidebar were not sticky — caused by items-start on the flex container collapsing aside height; removed items-start so asides stretch to article height

Single post left and right sidebars were pushed to page edges because center column used flex-1 (consumed all space); changed to w-full max-w-2xl with justify-center so sidebars hug the article

Section dividers and borders throughout the blog page softened — dark mode uses gray-700/800 instead of near-white; light mode uses gray-100/200 instead of bold gray-900 lines

Category sections now show 6 posts per section (1 lead feature + 5 stacked mini-cards) for better left/right column balance

IndexNow CMS page (/polaris/indexnow) — bulk-submit any combination of blog posts, lessons, grammar pages, quizzes, and static pages to Bing/Yandex/other search engines with one click

IndexNow key file hosted at /c1c02929ad4d4c7ba63a4561cc5e83b5.txt for domain ownership verification

Blog page redesigned with Atlantic/every.to-inspired editorial layout — compact max-width container (max-w-4xl), left/right breathing margins, bold masthead, 2-column hero with numbered "More Stories" list, Atlantic-style thick-rule section headers per category, and lead feature + stacked mini-card layout for each category section

Category filter pills updated to minimal black border / filled style matching editorial aesthetic

Culture Picks slider now contained within the max-width grid with rounded corners rather than full-width bleeding

Blog category sections now always show all posts — previously, if the newest post in a category became the hero or a side story, the entire section appeared empty

Multi-category posts (e.g. tagged as both Culture and Arts) now appear in every category section they belong to, not just the Culture slider

Content Visualizer now auto-clusters posts under pillars — posts in the same category as a pillar group automatically without needing a manual assignment; tag and keyword overlap breaks ties between multiple pillars in the same category
