The cube view-transition block moves out of pagerite.css into transition
designs (pagerite/themes/{name}/transition.css), handled like banner
designs: served from disk at /_themes/..., injected by the backend as
#pagerite-transition after the banner sheet, and picked site-wide in the
site settings (Data.transition, default cube; GET/PUT /_api/settings
carry transition + the designs found on disk). The site editor swaps the
sheet in place on change; the dev-mode order fixup knows the new id.
Designs: cube (unchanged), crossfade (all navigations), slide (sideways,
both pages moving together) and reveal (clip-path wipe over the
stationary old page) — the latter two mirrored on history-back and
crossfading within a section like cube.
Also compress the site settings form into a two-column grid: site name +
favicon on one row, theme + transition on the next.
Anchored h1/h2s carry data-line (markdown source line, top-level
headings only) and h2s get dimmed section pens that open the page
editor at that section. Editor scroll sync is now piecewise-linear
keyed on those anchors: the page follows the cursor (fractional,
wrap-aware, fixed window anchor; editor scroll no longer drives it),
the editor follows page scroll with a progress-based viewport anchor,
so document ends line up exactly in both directions. The editor always
follows the URL — fetch-navigation retargets it — with unsaved text
stashed per path for the session and restored on return. Banner pen
removed (the tab stays in the shell); top-right order is now
analytics, site settings, login/logout.
