Add speaker-labeled transcripts, favicon, host stream fix, episode page

- Re-label all 8 episode transcripts with LUKE:/CALLER: speaker labels
  using LLM-based diarization (relabel_transcripts.py)
- Add episode.html transcript page with styled speaker labels
- Update publish_episode.py to generate speaker-labeled transcripts
  and copy to website/transcripts/ for Cloudflare Pages
- Add SVG favicon with PNG fallbacks
- Fix CPU issue: tie host audio stream to on-air toggle, not per-caller
- Update how-it-works page with post-production pipeline info
- Add transcript links to episode cards in app.js

+LUKE: All right, welcome to the show. This is Luke at the Roost. This is the radio show where you call in and we talk about whatever's going on in your life We could talk about math or science or nerd shit or we could talk about somebody that pissed you off at work It doesn't really matter as long as what you have to say is interesting So give us a call the number here is 8 6 8 9 0 9 11 8 8. That's 8 6 8 9 0 9 11 8 8 Let's go to the phone and talk to Earl Earl. Give us a little bit about your interpretation of Schrodinger's cat
+
+EARL: Yeah, well Schrodinger's cat, you know, it's one of those Quantum physics things I guess Sounds like a bunch of mumbo jumbo to me. I mean the idea that the cat could be you know both alive and dead at the same time It makes my head spin. I'm more of a common sense kind of guy, you know Quantum physics, but if I can't see it or touch it, it ain't real as far as I'm concerned But hey, what do I know right? I'm just the old guy trying to make sense of all this newfangled science stuff Dearies and whatnot
+
+LUKE: Well kid, you can you see love? Can you see the hatred in your heart that you have for a well-known documented scientific theories?
+
+EARL: Oh Look at you trying to get all philosophical on me the heart. You can't exactly put those things under a microscope can you? No, this old dog ain't buying into all that touchy.
+
+LUKE: All right, you'll dog get off the air then Let's see who else we got Marcus. Marcus. Welcome to Luke at the Roost. Let's talk about some quantum physics stuff Give me give me your interpretation of the plank constant and what that means to the universe
+
+MARCUS: Geez, yeah, the plank constant. I mean, that's like some heavy stuff, you know? From what I remember, it's basically this fundamental unit of measurement that's tied to like the smallest possible changes in energy and matter Like it's the minimum possible action or something I don't know. It's kind of mind-bending when you think about it. How there's this Fundamental limit to how small things can get Makes you wonder what else is out there, you know like what else is going on in this crazy universe that we can't even wrap our heads around Oh, man, I could go on forever about this stuff, but Yeah, I don't know. It's just wild to think about you know
+
+LUKE: Let's talk about the speed of light for a second. So we have measured the speed of light It's pretty fucking fast everybody can agree on that, but what is its relationship to energy? Einstein had his famous Equation e equals mc squared which is energy equals matter times the speed of light squared Why is the number the speed of light showing up in other places in the universe and what could that relationship mean?
+
+MARCUS: You have light man. That's just nuts. I mean think about how fast that is, you know, it's like what 300,000 kilometers per second or something That's just insane and you're right. Einstein totally cracked the code with that e equals mc squared thing I mean the fact that the speed of light is so central to that equation. It's got to mean something, you know Like the way I see it. It's almost like the speed of light is this fundamental constant that's woven into the very fabric of the universe I mean it's not just about how fast stuff moves. It's about the relationship between energy and matter That's it. The speed of light is like the bridge, you know, it's what connects all that stuff together Man, I could go on for hours about this, but you're totally right. There's just something so profound about the role The speed of light plays in all of this. It's like the key to unlocking the secrets of the universe or something Wild stuff, dude.
+
+LUKE: Well, that's what we do here on Luke at the roost is we We crack open the secrets of the universe. So let's go to one more caller for our show today. We've got Rick Rick tell us how you feel about Let's see what was a good one for you Why isn't Pluto a fucking planet planet?
+
+RICK: Come on, man. What is this the 90s? Nah, look Pluto's just too small, you know, I mean it ain't even the biggest rock out of scientists got it right Pluto's just a dwarf. They just leave it alone, you know a dwarf planet sounds like a more awesome planet than just a planet Wouldn't you say because it's got, you know, the descriptor of a dwarf. It's it's more exciting
+
+LUKE: Yeah, I guess you got a point there. I mean a dwarf planet. That's got a little more flair to it, you know Sounds like something straight out of fantasy novel or something
+
+RICK: Yeah, I can dig it Pluto the dwarf planet has a nice ring to it It's just being some plain old regular planet Got to admit that does make it sound a little more. I don't know Special I guess there's no sleep over it. It is what it is Yeah, it's a planet Planet's are pretty cool even though there's you know innumerable planets out there that we all get to look at in the Dark beauty of the night around the desert
+
+LUKE: Tell me what you think about astrophotography and what Starlings doing to To get in the way of that with with their Starlink satellites in low Earth orbit
+
+RICK: Don't even get me started on that Starlink nonsense. I mean look I get there trying to bring internet to folks, but do they got a ruin the whole dang night sky for the rest of us? Me some good astrophotography, you know Sitting out in the desert looking up at all them star. It's damn near-peaceful, you know But then you got these Starlink satellites just half the time you can't even see the Milky Way anymore It's just they'd find another way to get internet out there that doesn't yeah, that'd be great But to be perfectly honest with you it hasn't really made any Impact at all in my night sky photography It's pretty cool to see the little sled of Starlink satellites shimmy across the night sky Especially the first time. I don't know. He's blows everybody's mind.
+
+LUKE: Anyway, we're gonna take one more call from Brenda Brenda tell me about your latest Relationship blunder
+
+BRENDA: Where do I even start? I mean, I met this guy at the grocery store He seemed nice enough, you know We went on a couple dates and I thought hey, maybe this could actually work out for once But then of course he had to go and mess it all up We were having dinner the other night and I mentioned wanting to get a dog and he just looked at me like I had three heads I mean who doesn't love dogs? It's a deal breaker, you know, I Don't know I just I can't catch a break with these guys I'm never going on another date again. I swear
+
+LUKE: Has anybody ever told you Brenda that you sound like Claire from last? Charlie Charlie, I don't want you around my baby, Charlie I am just a I serve no purpose on this island Charlie other than to complain about you and everything that you've done to save and protect me for no reason at all Charlie And I'm just mean to you all the time because I'm a fucking bitch Charlie stay away from my baby. I don't even want to be a mother
+
+BRENDA: Oh my god, are you serious? That sounds just like my sister Claire Like the uncanny resemblance to scary Always complaining always putting down the people who are actually trying to help her and the way she talks about her baby daddy Charlie It's the worst I swear the two of us could be twins sometimes. We're both just High-strung your rock your fucking bitches and you're off the air.
+
+LUKE: That's enough of you Everybody thank you for tuning in for this installment a look at the roost and we'll be back next week Be sure to tune in maybe we'll broadcast this shit over the ham radio But by or if why as they say
