5.3.55 — Per-page opt-out, content indent, vertical heading

Carries the complete content of 5.3.54 under a new version number.

The tag v5.3.54 was moved to the finished commit after publication. Packagist
had already registered the previous commit and rejects changes to published
stable versions, so composer require t3sbs/t3sbootstrap:5.3.54 installed the
5.3.53 code (see #529). The code here is identical to the intended 5.3.54 —
only the version number, the changelog and the release notes changed.
Anyone who installed 5.3.54 via Composer should update to 5.3.55.

Highlights

Per-page opt-out — a new T3SB tab in the page properties switches off
navbar, meta line, breadcrumb, page title, jumbotron and footer for a single
page, without touching the site configuration.

Content indent — a page indents its content elements by 1 to 6 grid
columns, from lg up, in the one-column layout. Subpages inherit the value.

Vertical heading — the heading block of the background wrapper rotates by
90 degrees, read upward or downward.

RTE text colours — the six Bootstrap text colours are now a toolbar
dropdown instead of twelve style entries, and visible in the editor.

Fixed

• Missing backend layout on pages with a workspace version record
• Two outdated SRI hashes that blocked Bootstrap CSS and JS in CDN mode
• Dropdown slide-in and fade never ran (removed-animate-1 instead of dd-animate-1)
• Tables lost their Bootstrap base class table after editing in the RTE
• Border option "line above/below" had no effect on wrappers
• Backend stylesheet distorted the card grid in all modules (#527)
• Offcanvas menu: class undefined, search field, label alignment
• Debug template removed from the container folder

Upgrade

Nine new columns — seven in pages, two in tt_content. Run the database
analyser, flush the caches, then save the configuration record once.

Requires TYPO3 ^14.3, PHP 8.2 – 8.5.
