"""TOOL_PACKS: advertise only the vertical packs a client uses; core is always on.

v1.6 track E adds the `settings` pack: the 22 SECTION 20 environment tools.
Styles (SECTION 18) and page setup / templates (SECTION 19) are drafting
essentials and stay in `core`, so `TOOL_PACKS=core` hides the environment
surface and nothing else.

v1.6 tracks B+G add the `mech` pack: SECTION 21's six part-model tools and
SECTION 22's three standard-parts tools and SECTION 23's five annotation
symbols - 14 in all. SECTION 24 (the sheet: frames, title blocks, revisions,
the parts list, balloons, xrefs, images, DWG) stays in `core` - universal
drafting, not a vertical - and files under its own `sheet` group.
