The new-tab page is now a two-column desktop. The right column holds the
curated Silent Mode X-family (Theseus.X, SilentMode.X, Sirius.X,
Hephaestus.X, Prometheus.X, Hermes.X, Helios.X, Ariadne.X, Aegis.X) with
real brand marks pulled from each product's own favicon or add-on manifest.
The left column is yours — hello.bch, sia.coin, Pithos.sia, Bergamot.X by
default, plus whatever you add. Icons pick up and move within and across
columns in edit mode.
Edit mode also carries per-column default-size pickers (S / M / L / XL),
six background presets + a custom colour + an image upload, and + slots
in each column. The Ariadne.X mark uses the real face/thread illustration
in ancient-Greek-pottery colours (terracotta rings on cream). The Aegis.X
tile matches the one the add-on itself ships.
The on-disk format moves from a bare array of cards (v1) to a v3 object:
{ version:3, iconSize, quickSize, background, sections:{ sm, q } }
On first read, a v1 array lands as sections.q and the Silent Mode column
stays at the code default. The remote home-cards.json URL is still
accepted as either shape; migrateCards() normalises before use.
