/* `.tab-bleed` is a thin wrapper around `.tab-body` whose job on wide viewports
 * is to escape #app's `--content-max` lane and provide a centered, viewport-wide
 * playground inside which `.tab-body` shrinks to fit its (post-wrap) content.
 *
 * Why a wrapper at all: we want the FRAME (the bordered pre) to be exactly as
 * wide as the longest line of the wrapped text — not always the full lane. The
 * bleed lane gives chord-wrap.js the budget to consider for wrapping; once it's
 * wrapped, `.tab-body { width: max-content }` collapses the frame to the real
 * widest line. Flex-centering on `.tab-bleed` puts that frame in the middle.
 *
 * Bleed math: parent (#app) is centered at `--content-max`, so its left edge
 * sits at `(100vw - --content-max) / 2`. To pull the bleed's left edge to
 * `(100vw - --bleed-max) / 2`, the offset from parent's left is
 * `(--content-max - --bleed-max) / 2` — that's the negative margin-left below. */
