fix: make page title <h1> conditional to prevent double headings (v1.0.3)

When plugins inject content via TwigService with empty post.title,
the theme's <h1> is now skipped. Prevents duplicate headings on
plugin-rendered pages that provide their own titles.

+## [1.0.2] - 2026-02-10
+
+### Fixed
+
+- Missing HTML `<title>` tag on all pages — theme never declared `add_theme_support('title-tag')`, so WordPress's `_wp_render_title_tag()` hook was inactive during `wp_head()` output in Twig templates
+
+## [1.0.1] - 2026-02-09
+
+### Added
+
+- Bootstrap Icons web font integration — all 2,000+ icons available via `<i class="bi bi-*"></i>` CSS classes
+- `copy:icons` build step to copy icon font files (`.woff`, `.woff2`) from `node_modules` to `assets/fonts/`
+- Bootstrap Icons SCSS imported in both frontend and editor stylesheets for icon support in templates and block editor
+
+## [1.0.0] - 2026-02-08
+
+### Added
+
+- Sidebar widget area (`primary-sidebar`) registered via `register_sidebar()` — manageable in Appearance > Widgets
+- Widget area rendering in Twig sidebar with fallback to built-in content (recent posts, search, tags) when no widgets assigned
+- Widget area description strings added to all translation files (en_US, de_CH, fr_FR)
+
+### Changed
+
+- Updated README.md with accurate feature counts (15 style variations, 41 patterns, 3 translations)
+- Added documentation for style variation bridge, widget areas, RTL support, and accessibility features
+
+## [0.3.3] - 2026-02-08
+
+### Fixed
+
+- Style variation colors not applied to Bootstrap frontend — bridge function checked wrong palette origin (`custom` instead of `theme`)
+- Variation detection now compares `theme` origin against base theme.json defaults instead of looking for slugs in `custom` origin
+
+## [0.3.2] - 2026-02-08
+
+### Fixed
+
+- Dark mode body colors overridden by WordPress global styles (`styles.color` in `theme.json` generated conflicting `body` CSS)
+- Dark mode styling for plugin-generated form elements (`select`, `input`, `textarea`) that lack Bootstrap classes
+- Footer columns template used hardcoded `bg-dark text-light` instead of semantic `bg-body-tertiary`
+- Style variation bridge function ran with default palette when no variation was active, causing unnecessary CSS overrides
+
+### Changed
+
+- Removed `styles.color` from `theme.json` to prevent WordPress from generating body background/text CSS that conflicts with Bootstrap dark mode
+- Added `!important` override in `_custom.scss` for `html[data-bs-theme="dark"] body` to ensure Bootstrap dark mode takes precedence
+- Added broad dark mode rules for native form elements in `_custom.scss`

 ## Session History
 
+### Session 11 — v1.0.3 Conditional Page Title (2026-02-11)
+
+**Completed:** Made `<h1>` on page template conditional to prevent double headings when plugins provide their own titles.
+
+**What was fixed:**
+
+- `views/pages/page.html.twig` now wraps `<h1>{{ post.title }}</h1>` in `{% if post.title is not empty %}` guard
+- When a plugin passes empty `post.title` via `render_via_theme_twig()`, the theme's `<h1>` is skipped
+- Prevents duplicate headings on pages where plugin templates render their own `<h1>` with richer context (icons, badges, meta)
+
+**Key learnings:**
+
+- Plugins that delegate rendering to the parent theme via `TwigService` should be able to opt out of the theme's `<h1>` by passing empty `post.title`
+- The `is not empty` Twig test correctly handles both `null` and empty string `''`
+
+### Session 10 — v1.0.2 Title Tag Fix (2026-02-10)
+
+**Completed:** Fixed missing HTML `<title>` tag on all pages rendered by the theme's Twig pipeline.
+
+**What was fixed:**
+
+- Added `add_theme_support('title-tag')` to `wp_bootstrap_setup()` in `functions.php`
+
+**Root cause:**
+
+- The theme's `base.html.twig` calls `{{ wp_head() }}` which fires the `wp_head` action
+- WordPress hooks `_wp_render_title_tag()` to `wp_head` at priority 1, which outputs the `<title>` tag
+- However, this hook only fires when the theme declares `add_theme_support('title-tag')`
+- The theme never made this declaration, so `wp_head()` output included styles and scripts but no `<title>` element
+- All pages rendered by `TemplateController` (via `base.html.twig`) were affected
+
+**Key learnings:**
+
+- `add_theme_support('title-tag')` is required even for themes that render `wp_head()` via Twig — WordPress does not output `<title>` without it
+- The absence of a `<title>` tag is invisible in the rendered page but affects SEO, browser tab display, and bookmarking
+- This support declaration has been standard since WordPress 4.1 and should always be included in `after_setup_theme`
+
+### Session 9 — v1.0.1 Bootstrap Icons (2026-02-09)
+
+**Completed:** Bootstrap Icons web font integration via SCSS build pipeline.
+
+**What was built:**
+
+- Added `bootstrap-icons` npm dependency (v1.13.1)
+- Imported Bootstrap Icons SCSS in both `style.scss` and `editor-style.scss`
+- Added `$bootstrap-icons-font-src` variable override in `_variables.scss` to point `@font-face` at `assets/fonts/`
+- Added `copy:icons` npm script to copy `.woff`/`.woff2` font files from `node_modules` to `assets/fonts/`
+- Updated `build` script to include `copy:icons` step
+
+**Key learnings:**
+
+- Bootstrap Icons SCSS uses `$bootstrap-icons-font-src` to allow overriding the `@font-face` `src` declaration — set it before the import to control font file paths
+- The existing `--load-path=node_modules` Sass flag resolves `@import "bootstrap-icons/font/bootstrap-icons"` without any extra configuration
+- Font files (`.woff2` at 131KB, `.woff` at 176KB) are small enough to serve as web fonts without performance concern
+
+### Session 8 — v1.0.0 Release (2026-02-08)
+
+**Completed:** Sidebar widget area registration, Twig widget rendering with fallback, documentation refresh, v1.0.0 release.
+
+**What was built:**
+
+- `register_sidebar()` for `primary-sidebar` widget area with Bootstrap-styled wrapper markup
+- Widget area rendering in `ContextBuilder::getSidebarData()` via `ob_start()` + `dynamic_sidebar()` with fallback to built-in content
+- Twig sidebar template conditional: renders WordPress widgets when assigned, falls back to recent posts/search/tags otherwise
+- Updated README.md with accurate feature counts (15 variations, 41 patterns, 3 translations, accessibility, RTL, widget area)
+- Updated all translation files (.pot, de_CH.po, fr_FR.po) with widget area strings
+
+**Key learnings:**
+
+- `is_active_sidebar()` returns true only when widgets are assigned to the area, making it the right condition for fallback logic
+- `dynamic_sidebar()` outputs widget HTML directly, so `ob_start()`/`ob_get_clean()` is needed to capture it for Twig
+- Widget area `before_widget`/`after_widget` markup should use Bootstrap utility classes (`widget mb-4`) for consistent spacing
+- Widget title markup (`before_title`/`after_title`) should match existing sidebar heading styles (`sidebar-heading h6 text-uppercase fw-semibold`)
+
+### Session 7 — v0.3.2/v0.3.3 Dark Mode & Style Variation Bridge (2026-02-08)
+
+**Completed:** Fixed dark mode rendering conflicts between WordPress global styles and Bootstrap, fixed form element styling in dark mode, bridged style variation colors to Bootstrap CSS custom properties, fixed variation detection to read from correct palette origin.
+
+**What was built:**
+
+- Style variation bridge function (`wp_bootstrap_variation_colors`) that maps WordPress palette colors to Bootstrap CSS custom properties via `wp_enqueue_scripts`
+- Helper functions for color manipulation: `wp_bootstrap_hex_to_rgb()`, `wp_bootstrap_build_surface_css()`, `wp_bootstrap_mix_hex()`, `wp_bootstrap_hex_to_rgb_array()`, `wp_bootstrap_relative_luminance()`
+- Variation detection comparing `theme` origin palette against hardcoded base defaults (base, contrast, primary)
+- Dark mode body override in `_custom.scss` using `!important` to defeat WordPress global styles specificity
+- Broad dark mode rules for all native form elements (`select`, `input`, `textarea`) to catch plugin-generated controls
+- Fixed `footer-columns.html.twig` to use semantic `bg-body-tertiary` instead of hardcoded `bg-dark text-light`
+
+**Key learnings:**
+
+- WordPress puts style variation colors in the `theme` palette origin, NOT `custom` -- `wp_get_global_settings(['color', 'palette', 'theme'])` returns the base theme.json merged with the active variation
+- The `custom` palette origin contains user manual edits from the Site Editor, but its data structure may lack expected `slug`/`color` keys
+- To detect an active variation, compare `theme` origin colors against known base theme.json defaults rather than checking for slugs in `custom`
+- WordPress `theme.json` `styles.color` generates `body { background-color: var(--wp--preset--color--base) }` directly on `body`, which overrides inherited CSS variables from `html[data-bs-theme="dark"]` -- removing `styles.color` from theme.json is the cleanest fix
+- CSS variables defined directly on `body` beat inherited values from `html` due to specificity, requiring `!important` on `html[data-bs-theme="dark"] body` to ensure Bootstrap dark mode works
+- Plugin-generated form elements (e.g., `<select class="jr-search-form__filter-select">`) lack Bootstrap classes and need explicit dark mode styling via element selectors
