The HTML→PDF path produced PDFs where content extended past the
right margin of each letter page. Two contributing causes in
viewer-template.html's @media print rules:
1. .content-wrapper carries max-width: min(900px, 100%) from the
screen layout. The print override set width: 100% but didn't reset
max-width. Chromium's --print-to-pdf renders at the full page
width (816px for letter at 96dpi) and only clips at print time,
so without max-width: none the element actually extends past the
~624px printable area.
2. Tables, preformatted blocks, and long URLs had no print
containment. A wide <pre> or a <table> with many columns would
blow out the right edge even when the parent constraints held.
Fixes applied to @media print:
- html, body, .app-container: explicit width: 100% + max-width: 100%
to be sure the print viewport flows top-down with no horizontal
creep at the layout root.
- .content-wrapper: max-width: none + width: 100% (was just width).
- .content-page: width: 100% added (was just max-width: none).
- .document-content: max-width: 100% + box-sizing: border-box so
the existing 0.5in horizontal padding stays inside the page.
- pre/code/table/blockquote/img/video: max-width: 100% +
overflow-wrap: break-word; <pre> additionally white-space:
pre-wrap + word-break: break-word so unbreakable token runs
(URLs, paths, command lines) wrap instead of overflowing.
- table: table-layout: fixed so columns shrink to fit rather than
forcing horizontal scroll/overflow.
