v0.0.339

Fixed

• /runs had 0px under its last run row where every other list page gets 64px. It
  was in FULL_HEIGHT_ROUTES, so PageTransition gave it min-h-0 and withheld
  PAGE_CLEARANCE - and it stopped being a full-height route in #914: the page's root
  is an ordinary scrolling flex flex-col and the run detail is sticky inside the
  page's own scroll rather than a pane with a scrollbar of its own. One regex was
  answering two different questions on the page's behalf, so it is two now:
  OWN_SCROLL_PANE (/chat alone, which needs the constrained chain so the transcript
  scrolls instead of the page) and OWN_BOTTOM_ROOM (/chat and /runs, both having
  something that must reach the bottom edge). Activity then declares PAGE_CLEARANCE
  one level in, on its list column - and that placement is the whole point, because
  padding on the box around the two-column row shortens the containing block the
  sticky panel is clamped to. Measured at 1440x800 against a transcription of the
  page's own chain: room on the outer box gives 64px of clearance and a panel top of
  -48px with its header cut off by 56px, which is the figure in the issue; room on
  the list column gives 64px and a panel pinned 8px from the window top, header
  visible. (#1206)
• Below lg, the run detail panel's last 56px sat behind the mobile tab bar. The
  list column is hidden there and the panel is the only column, so its flat
  h-[calc(100dvh-1rem)] ran under a bar that is fixed bottom-0, min-h-[56px] plus
  the safe-area inset. Measured at 390x780: 56px hidden before, 8px clear after, which
  matches the 8px it already keeps at the top. The full height stays above lg, where
  the bar is hidden. Same element, two lines, so it is here rather than in a second
  change. (#1206)
• page-transition.test.tsx was asserting the old reason - "constrains Activity too,
  where the list and the run detail scroll apart", true before the page was rebuilt and
  false since. It asserts both halves of what is true now: no min-h-0, and no pb-
  either, with the prefix-match case still checking that /runsomething gets the
  room. (#1206)
