FredApps: AGENTS.md §1.4 allows reading an installed font at runtime only as
the interface's last fallback and says nothing from it may enter a PDF or
package, while the renderer fallback also served exports and printing.
RenderConfig gains system_fonts, off by default. The engine sets it only on the
pool that draws the viewer (display_config); exports, printing, OCR and the
automation tools render with the document's own configuration, so nothing drawn
with an installed font is saved or printed. Tests: the render of a non-embedded
CNS1, GB1 and Korea1 font is blank without the flag and drawn with it; the
viewer's pool draws such a page and an export of it does not (it fails if the
flag is on everywhere). No Adobe-named font can be a candidate.

CodeRabbit: on recent macOS the PingFang collection is not in
/System/Library/Fonts but in the downloaded font assets
(/System/Library/AssetsV2/com_apple_MobileAsset_Font*/<id>.asset/AssetData), so
the fixed path missed it, and the PingFang test returned early without checking
anything on such a machine. The macOS candidates now include the AssetData
folders of those assets (listed once, at most 512 per kind), and a test
searches the assets independently and requires the candidate list to contain
what it finds.

CodeRabbit: the fallback cache was keyed by (script, weight) and every key read
and kept its own copy of the file, so PingFang.ttc (tens of megabytes, a
candidate of several scripts and both weights) could be held up to four times.
The bytes now come from a process-wide cache keyed by path, remembering files
that cannot be used too; the per-script cache keeps a handle and a face index.

A CID font of an Adobe CJK collection (Japan1, GB1, CNS1, Korea1) that the PDF
doesn't embed drew nothing unless craft-fonts had a Japanese face: text boxes
from Acrobat (Kozuka Gothic) and Pages (SongtiTC) were blank. After craft-fonts,
the renderer now uses one face already installed on the machine, read at
runtime and never bundled. The face of a multi-region collection (PingFang SC
or TC) is chosen by region. Noto CJK and Source Han are not candidates, and
PDFCRAFT_SYSTEM_FONTS=0 turns it off.
