v1.1.4

Scaffold robustness: fixes so a shipped artifact cannot overflow horizontally (which fired the runtime layout-audit banner and clipped content on a phone).

• .meta-ribbon span was white-space:nowrap, so a single long value (e.g. a wordy Status) could not wrap and pushed past a 390px phone viewport. Now white-space:normal; overflow-wrap:anywhere; short label/value pairs still sit together, only an over-long value wraps internally.
• .bars misused as a definition list no longer blows out the page. .bars dd now carries min-width:0; overflow-wrap:anywhere so a <dt>/<dd> prose list fed into the progress grid degrades instead of forcing a max-content column.
• New .deflist component for the label + wrapping description pattern (risks, key terms, glossary rows, a chip plus a paragraph). references/diagram-types.md and references/patterns.md steer authors to it and warn against .bars for prose.
• New figure.diagram / .diagram-scroll / .diagram-src scaffold styles for shipping a diagram as inline SVG (self-contained under Quick Look, email, offline) with the source in an adjacent <details>.
• Scrub two — that rendered a visible em dash in emitted output (the gallery lede and the review scaffold body).

Verified with a real headless-Chrome measurement at 390px and 1280px: the fixed scaffold has zero true overflow sources; reverting the fixes reproduces the 1491px blowout.
