Dark Theme Overhaul

What's Changed

Complete Dark Theme Overhaul (#365)

A ground-up rewrite of the dark theme for a modern, consistent, and readable experience.

Changed

• Replaced ad-hoc grays ([#222](https://github.com/QuantEcon/quantecon-book-theme/issues/222)/[#333](https://github.com/QuantEcon/quantecon-book-theme/issues/333)/[#444](https://github.com/QuantEcon/quantecon-book-theme/issues/444)) with a cohesive navy-charcoal palette (#1a1a2e background, [#252540](https://github.com/QuantEcon/quantecon-book-theme/issues/252540) surfaces, #d4d4e4 text, #6cb6ff links)
• Images now use subtle opacity reduction instead of aggressive CSS inversion
• CSS custom properties — all 16 palette colors declared as overridable --qe-dark-* custom properties; downstream projects can now customize colors without duplicating selectors

Added

• Dark mode syntax highlighting — complete token colors for all ~40 Pygments syntax classes using a VS Code Dark+ inspired palette
• FOUC prevention — early inline script applies dark mode class before first paint, eliminating the flash of white on page load
• Dark mode documentation — new "Dark Mode" section in configure.md covering palette, syntax highlighting, admonitions, image handling, and CSS customization with full reference table of all overridable custom properties
• Dark mode coverage for unstyled elements — modals, admonitions (type-specific accents), homepage elements, collapse/toggle bars, tooltips, autodoc, footnotes, and non-QuantEcon project overrides

Fixed

• Double logo in dark theme — when a dedicated dark logo is configured, both light and dark logos were shown
• Page header unreadable in dark mode — title link, authors, "Last changed" button, and changelog dropdown used [#444](https://github.com/QuantEcon/quantecon-book-theme/issues/444) text on dark backgrounds
• Unreadable table text in dark mode — table rows used [#333](https://github.com/QuantEcon/quantecon-book-theme/issues/333) text on dark backgrounds
• Indistinguishable links in dark mode — all links were #fff, same as body text
• Inline code light border in dark mode — code spans retained light-theme borders
• Sidebar search white in dark mode — search input area remained white
• Toolbar border in dark mode — toolbar border remained light gray
• Syntax highlighting gaps — only 3 of ~40 token types had dark mode overrides
• Stderr warnings in dark mode — updated to use amber accents matching the new palette

Full Changelog: QuantEcon/quantecon-book-theme@v0.17.1...v0.18.0

v0.17.1

Bug Fixes

Fixed

• Horizontal scrollbar on sticky TOC (#363) — added overflow-x: hidden to the sticky "On this page" sidebar to prevent an unwanted horizontal scrollbar when long section titles wrap
• npm security vulnerabilities (#364) — resolved 9 dependency vulnerabilities (5 high, 3 moderate, 1 low) via npm audit fix, updating webpack, node-forge, qs, lodash, cross-spawn, ajv, and nanoid

v0.17.0

Sticky TOC & Color Scheme System

Breaking Changes

• Removed individual color options — emphasis_color, emphasis_color_dark, strong_color, strong_color_dark, definition_color, definition_color_dark have been replaced by the new color_scheme option. Migrate to the built-in seoul256 scheme or a custom_color_scheme.css file.

Added

• Sticky table of contents with scroll highlighting (#350, #133)
  • sticky_contents option enables a fixed-position RHS TOC that tracks scroll position
