The width tier, title-border arithmetic, ON/OFF/DEFAULT badge, cursor cell
and table row are currently hand-copied across the three draw functions.
This adds them once, with the two geometry identities derived rather than
hand-maintained: a row's chrome is a fixed 21 columns, so field_w is
iw - 21 - label_w (reproducing both iw-33 and iw-34), and a title border is
dashes = iw - visible(segment) - 1 (reproducing all three of iw-23,
iw-len-3 and iw-L-S-22).
The frame owns no page height. Every verb prints exactly one line or
fragment, so the fixed-16 category and value pages and the dynamic
7+n sub-category page keep their heights, and config-settings.fish's
erase is unaffected.
No caller yet, so rendering cannot move: the golden's existing page
section is byte-identical (verified with cmp -n over its previous size)
and the file only gains frame-verb cases appended after it.
