* docs: improve sidebar and TOC readability + scroll progress - Fix left nav sidebar hugging the left edge (remove margin-left) - Increase sidebar font sizes and lift muted colors for legibility - TOC right-side: white inactive items, pink active, gray for passed sections - Add clientModule (tocProgress.js) to track scroll progress in TOC - Add Redocusaurus API page styles to match site theme Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> * docs: fix sidebar/TOC height stability and active item reflow - Force sidebarViewport to 100vh to prevent shrinking during scroll - Replace font-weight on active TOC item with text-shadow to avoid reflow * docs: left-anchor sidebar and increase fonts on large screens * docs: constrain prev/next nav to match content max-width * docs: fix sidebar jump on scroll by moving padding-top inside menu * docs: fix sidebar-ad spacing with transparent padding on li * docs: fix sidebarViewport height and MutationObserver leak * docs: constrain doc content to 75vw and remove dead CSS comments - Cap docMainContainer at 75vw - Set pagination-nav to 100% width to match content column - Remove commented-out .markdown and .ch-scrollycoding blocks * docs: set docMainContainer max-width to 75% for better reading width * docs: center main-wrapper on large screens and center docItemWrapper * fix: revert lodash override to stable 4.17.21 lodash 4.18.0 is a broken release — template.js uses assignWith and arrayEach without importing them, crashing npm start. Pin to 4.17.21 across all nested overrides. * fix: prevent horizontal scroll on mobile docs pages docsWrapper has flex:1 0 auto (flex-shrink:0), so it never shrinks below the natural content width (~570px on iPhone). Cap it to 100vw and add min-width:0 down the flex chain (docRoot, docMainContainer) so the layout stays within viewport on narrow screens. Also remove the overflow:visible override from ch-code-wrapper, which was defeating the code block's own horizontal containment. * feat: responsive navbar search and hide social icons on mobile Shrink search bar as viewport narrows (160px at 1100px, 100px at 996px), collapse to icon-only at 960px. Hide GitHub, X, and Discord icons below 996px where the hamburger menu takes over navigation. * fix: images always respect container width above 996px Use min(100%, 600px) so images are capped at 600px but never overflow their container when the content area is narrower (e.g. sidebar open). * fix: improve TOC progress scroll tracking and bottom-of-page detection Adds scroll handler with RAF throttle, pauses/resumes MutationObserver to avoid loops, and forces last TOC link active when scrolled to page bottom. * fix: translate Portuguese comments to English in custom.css * fix: sidebar viewport fills full screen height * feat: sidebar section icon turns pink with ease transition when active * fix: reduce TOC font size to 0.8rem * fix: remove docMainContainer right padding and add 48px gap to content col * fix: card header responsive alignment and title margin reset * fix: darken card background and active sidebar item bg on light theme * fix: revert TOC colors and add inline code border radius tweak * fix: minimal scrollbar for sidebar and TOC — thumb only on hover * fix: scrollbar fade-in/out transition at 0.25s ease * feat: add rehype plugin for table column wrapping and centering Inserts zero-width space after underscores in inline code cells so long env-var names wrap at underscore boundaries. Also centers Format/Default columns via a col-center class applied at build time. * fix: use --ifm-heading-color for sidebar group labels in both themes * refactor: split docs custom.css into themed partials Breaks the 1,658-line monolithic custom.css into 8 focused files (tokens, layout, navbar, sidebar, typography, components, code, redocusaurus). custom.css is now a thin entry point with @imports. * fix: align sidebar and navbar with shared --docs-gutter token Introduces --docs-gutter: 1rem in tokens.css and applies it to both navbar__inner horizontal padding and sidebar nav.menu padding-left, keeping the Langflow logo and sidebar items visually aligned. * fix: match sidebar ad background to page background color Dark mode uses #111 (same as sidebar bg); light mode uses --ifm-background-color. --------- Co-authored-by: Claude Sonnet 4.6 <noreply@anthropic.com>
