So, this is a CHA martial with a lot of focus spells. They have standard martial stats.
Spotlight and Roles are very high complexity. I see what they're going for here, but juggling spotlights to keep them active might be complicated. Some very good effects in the roles though, and being able to debuff any save on demand without a saving throw is huge. Romance is a great way to help whoever's taking fire, etc.
I do note however that this class has no damage bonuses. This is somewhat offset by the focus spells... but a martial with no damage boost is in an odd place. Envoy is a comparison point here, but Get Em is a potent party buff and they bring some other major utility with directives, so that's the bar for Luminary to meet.
Platforms feel underwhelming. The bonus effects for hardlight props are kind of narrow (and it's unclear what Contest even does at all, exactly). Bonus skill training is standard... it's mostly just picking which set of focus spells you'll have and which free first level feat.
Speaking of, the first level feats are all kind of underwhelming. They all give you bonuses for setting a role on yourself and let you set it as a free action. That's great, but the bonuses are mostly ways to use Performance for other things, and a lot of them basically don't do anything else (they turn off the penalty for those roles, but... several feel kind of situational - Drama Maven is something I can't see basically anyone actually excited for as an example).
The higher level feats are more interesting. Some action compression at level 2. Blooper at level 4 is nasty, as enemies critically miss quite often (because they often make attacks with MAP). Most of them are pretty good at 4 actually, though Guest Cameo is the standout imo because it's a really good focus spell. Trope Deconstruction at 8 is really neat and opens a lot of potent options (reversed Romance is Get Em, reversed Irony can open an enemy up hard to spells, etc).
The meat of the class is definitely in its focus spells though. Going down the list of platforms...
Contest offers a really good buff to start out. Since it counts any and all checks, it means they get a +1 to their next attack any time they miss. It doesn't limit how many of these +1s can be floating at a time and it eventually goes to +2 at high levels. Highly poachable for other platforms imo. The wheel is fascinating - lots of powerful effects, unclear if that's each creature can spin it per turn or only the first... and the star contestant should be spinning that every time to rack up the buffs and explode enemies. Comparatively, Summon a Friend is functional but unexciting... mostly because it's never going to top the Wheel. Of. SUPERSTARS. It's a good reaction.
Fashion gives your target a great third action choice in forcing enemies to save against clumsy over and over. Can't go wrong with that. Getting two targets at once is a nice upgrade. I'm honestly not sure how to evaluate the other two. Catwalk is interesting but might be best suited to locking enemies into an area or something. Strut and Pose feels weak for a 6th rank spell?
Music is another third action with its unique role. The only thing is, 1d4 isn't much. It's not nothing either, but... hmm. It averages out to slightly ahead of character level or so though, which... I guess that makes it functional. Interestingly, it encourages putting this on yourself with the second spell. But... Fascinated remains one of the worst conditions, though this is a valiant attempt at making it work since you can rob multiple enemies of actions easily. It needs to specify whether allies can attack them without breaking it or not... and I suspect not, which, well. There's a reason Fascinated isn't very good. Grand Crescendo on the other hand is great, no notes. Damage enemies, allies get temp HP, it's a big AoE and no reason I wouldn't use this liberally.
Sports is for striking. That's a powerful rider to the first attack each round, but the temp HP never refreshes and doesn't scale at all, which feels odd. Big Game is moving damage areas and does very good damage over time. Grand Slam is fantastic and I will never not like "I cast Barbarian at you" effects. And for only one action with multiple bonuses to hit this is easily the best version in SF2 or PF2 and uh... wow. Sports is juiced, imo.
Theater is odd. The role is a double edged sword, because pulling people in to make everyone off-guard to everyone is a good way to make things quick and bloody. I don't know that I ever want to use this. Soliloquy however is great. Just give people Romance and move on, because making them harder to hurt while being able to heal repeatedly for double their level? Very nice, but it upstages Diva a bit. A lot of other interesting options here and you need to have a flash card for the lead actor if you stack this on them because they'll do this every turn for all sorts of goodies. Final Confrontation is doubling down on the quick and bloody though. ...I don't know how I feel about this platform because it's the biggest double edged sword and nothing else it feels like.
A special shout out to Cameo Appearance for the non-platform spells. Illusory Creature is a great and versatile spell and this casts it for less actions... and it's better since there's no disbelieving it. It can be blown up, of course, but still, summoning a turret with its own MAP to pew pew a bunch is fantastic and I'd take this 11 times out of 10?
