Introduce two new Mustache-style HTML fragment files that render a checkbox table for selecting news items associated with a record, keeping the markup out of PHP and in the template layer.

Core changes:

1. Associated news table wrapper (admin-news-asso-table.html):

2. Renders an sl_form table element with {{{ rows_html }}} slot

   • rows_html is populated by iterating admin-news-asso-cell fragments
3. Associated news cell (admin-news-asso-cell.html):

4. Renders a single <td> with a named checkbox input

   • name: associated[], value: {{ cid }}, checked state: {{{ checked }}}
   • Displays article title {{ ctitle }} as inline label text

Benefits:

• Separates HTML structure from PHP controller logic
• Reusable fragments composable via getHtmlFrag() calls
• Consistent with existing admin fragment template conventions

Technical notes:

• Triple-brace {{{ }}} used for pre-rendered HTML slots (rows_html, checked)
• Double-brace {{ }} used for plain-text values (cid, ctitle) requiring escaping
• Backward compatible: fragments are new additions, no existing files changed

Add a set of small, focused helper functions that generate reusable HTML fragments for admin panels, keeping presentation logic in helpers and out of individual module files.

Core changes:

1. New UI helper functions (core/helpers.php):
2. getTplAdminSmallNote(text): standalone sl_small note div for label-less form rows
3. getStopText(stop): joins non-empty error/stop messages with <br> separators
4. getTplAdminTextLink(href, label, ...): safe anchor tag for use inside raw HTML slots
5. getTplAdminTipLine(key, val): one key-value line for tooltip content_html strings
6. getTplAdminInfoLine(label, value): one label-value line for info block content
7. getTplAdminTableHead(cols): builds <th> head_html from column label arrays
8. getTplAdminTableCells(cells): builds <td> cells_html from pre-rendered cell content array
9. getTplSpan(class, raw_content, title): inline span with CSS class and optional title
10. getTplAdminStatusBadge(state, yes, no): sl_green/sl_red badge span for status display

Benefits:

• Eliminates repetitive inline HTML string construction across modules
• Centralises HTML-escaping rules in one place, reducing XSS risk
• Provides a consistent API for all admin panel fragment generation

Technical notes:

• All attribute values are escaped via htmlspecialchars with ENT_QUOTES/UTF-8
• raw_content in getTplSpan is intentionally not escaped (caller responsibility)
• Backward compatible: no existing signatures changed

shields.io path badges on GitHub were rendering incorrectly due to double percent-encoding of the space character (%20). Replaced %20 with underscore (_) which shields.io treats as a space and GitHub does not mangle.

Core changes:

1. Badge URL (README.md):

2. Replace %20 with _ in Migration badge URL

   • Prevents double-decoding of percent-encoded space by GitHub

Benefits:

• Badge renders correctly on GitHub

Technical notes:

• shields.io treats _ as space in path-based badge URLs
• %25 encoding for % sign is unaffected and remains correct

Introduce missing fragment and partial files required by the template engine after the admin helper and module migration, and add complete new layout and page files for lite and simple themes.

1. Admin fragments (templates//fragments/admin-.html):
2. Added admin-box, admin-form, admin-form-row, admin-form-wide, admin-table, admin-table-row

7. Added to all three frontend themes: default, lite, simple
8. Frontend fragments (templates/simple/fragments/):
9. Added account-, assoc-, basic-, block-, forum-, liste-, login-, shop-, voting-, users-, messagebox, navi, privat-message
10. Added to templates/default/fragments/ and templates/lite/fragments/ where missing
11. Layouts and partials:
12. Added templates/lite/layouts/main.html, templates/lite/pages/error.html
13. Added templates/lite/partials/alerts.html, login-logged.html, login-without.html
14. Added templates/simple/layouts/main.html
15. Added templates/simple/partials/contact-block.html, forum-teaser.html, menu.html
16. Added templates/default/partials/contact-block.html, forum-teaser.html
17. Modified existing fragments:

20. templates/admin/fragments/: updated admin-voting, admin-shop, admin-security, admin-rss, admin-replace, admin-media, admin-lang, admin-fields, admin-account fragments

Benefits:

• All template fragments required by migrated PHP helpers are now present
• Consistent fragment set across default, lite, simple themes
• No missing fragment errors at runtime after getTpl* migration

Technical notes:

• Fragments follow Mustache {{ }} and {{{ }}} slot conventions
• New admin fragments are identical across all three frontend themes

Remove all jQuery-dependent plugin bundles and replace core UI utilities with a standalone vanilla JS module, eliminating jQuery as a runtime dependency for all page-level functionality.

Core changes:

1. Plugin removal (plugins/):
2. Deleted plugins/jquery/ (jquery.js, jquery-ui.js, jquery.cookie.js, jquery.slaed.js, tinycon.js, ui/ bundle)
3. Deleted plugins/fancybox/ (jquery.fancybox.js and all helpers/assets)
4. Deleted plugins/uploadify/ (jquery.uploadify.js, uploadify.swf, assets)
5. Deleted plugins/ckeditor/adapters/jquery.js (jQuery adapter)
6. Deleted plugins/system/tablesort.min.js (moved to plugins/tablesort/)
7. Deleted plugins/codemirror/*/index.html (demo pages, not runtime code)
8. Added plugins/system/slaed.js (vanilla replacement for jquery.slaed.js)
9. Added plugins/tablesort/ (standalone tablesort bundle)
10. Template JS (templates/):
11. Deleted templates/lite/assets/js/jquery.bxslider.js
12. Added templates/lite/assets/js/tabs.js and templates/default/assets/js/tabs.js (vanilla tab init)
13. Updated theme.css in default and lite: removed BxSlider/jQuery UI styles, added vanilla tab CSS
14. Removed jQuery UI .ui-autocomplete CSS rule from system.css in admin/default/lite
15. Removed jQuery and jQuery UI badge links from layouts/app.html, layouts/home.html, index.html
16. Config and runtime (config/, core/system.php, plugins/system/global-func.js):
17. config/global.php: removed jQuery/FancyBox/Uploadify from script_f and css_f load lists
18. core/system.php: replaced jQuery UI datepicker in datetime() with native HTML5 input; fixed garbled UTF-8 in getTranslit() and filterSlug() transliteration maps
19. plugins/system/global-func.js: added vanilla syncNativeDateTimeInput() and fetchUserSuggestions() to replace jQuery UI autocomplete and datepicker
20. Encoding fixes (templates/*/fragments/editor-translate-panel.html):
21. Fixed garbled double-encoded Cyrillic characters in all four theme variants

Benefits:

• Eliminates jQuery and jQuery UI as page-level runtime dependencies
• Reduces total JS payload by ~30 KB (minified jQuery + jQuery UI)
• Resolves broken Cyrillic rendering in transliteration and editor panels
• Tab UI now works independently via vanilla setAdminTabs() and CSS

Technical notes:

• FancyBox (.screens, .site-link) still referenced in templates; requires separate replacement with native <dialog> or GLightbox
• CloseOpen(), HideShow(), Upper(), CheckBox(), TranslateLang() migrated to slaed.js as vanilla functions
• datetime() now emits native <input type="datetime-local"> with hidden sync field
