Here's the situation:
Bard takes Sorcerers Dedication Archetype
Question: How do feats gained via the Archetype affect the Bard spell repertoire?
This thread addressed metamagic feats:

The conclusion there is metamagic feats can be used on any spell, either from the base class or the archetype.
But what about non-metamagic feets?
Dangerous Sorcery - Has only the 'Sorcerer' tag. So it only affects spells gained from the archetype?
Cantrip Expansion - Has 'Bard' and 'Sorcerer' class tags. Would it affect both sets of cantrips or only those from the archetype?
