-- The mon inspector: species, level, DVs and moves for whatever S.editingMon
-- points at (a party slot or a box slot), all recalculated through MonOps so
-- stats stay in sync with the Gen1 formulas.
--
-- This used to be a modal overlay floating over the party list, which hid the
-- roster you were comparing against.  It is now a permanent right-hand column
-- the Party and Boxes panels dock into (rule 1 of the design spec): the list
-- stays visible while you edit, and Escape clears the selection rather than
-- "closing a window".
--
-- #715 reflow: the inspector used to shrink its stat tiles and DV/move rows
-- against a vertical budget, and past a point the rows still ran over the
-- action buttons.  Sizes are fixed at readable values now; when the card is
-- too short for them the whole body scrolls (Kit.scrollPixels), and when it
-- is too narrow for the DV | moves split the two columns stack.  The clip
-- over the card doubles as the hit fence, so a control scrolled out of view
-- cannot take a stray tap.
