The two client fixes for the Atlas frames Jeroen flagged. Region rung no
longer requests more planet than exists: cap_extent_to_body() caps the
viewport-fit extent at the body's own region grid (the Global canvas
extent echo — cols=regions_per_equator, rows=cols/2), matched by gridunit
SPACING not rung name, applied before the request/cache key is built;
cold-start scroll-before-Global-echo requests uncapped and lets the
server clamp (documented). Kills both the side-by-side continent repeat
and the past-the-pole stripe smear.
Global opener now fit-scales and centers through one shared letterbox
mechanism (center_offset/integer_fit_scale/fit_scale, 75%-coverage
integer-vs-fractional decision, NEAREST already forced on orbital rungs
per D-255's escape hatch) also used for the Region cap's letterbox
remainder. Legend column reserved before fitting — pinned to the legend's
own width by a cross-constant test, never overlapping the canvas.
Also fixes a latent crash: NOTIFICATION_RESIZED fires mid-_ready() before
children exist; null guard in the resize path.
