Add flex-shrink:0 to flipbook containers to prevent flex layout from
squishing them below pageW*2, which would trigger StPageFlip's
portrait (single-page) mode. Update rpubs page counter to show
spread page range (Pages X–Y of N) for middle pages.

StPageFlip injects its CSS (.stf__parent, .stf__block, .stf__item, etc.)
into document.head, which doesn't penetrate shadow DOM boundaries.
Pages rendered but were unstyled — collapsed/invisible. Replicate the
required rules inside each component's shadow root styles.

Visual overhaul of the rpubs editor and publish panel to match rpubs.online/press
design language: circular step indicators with checkmarks, SVG stroke icons on all
buttons, card-based publish panel with teal accent colors, pricing tier cards,
numbered DIY guide steps, group buy progress bar, and format info chips.
