merge main to prod (#553)

* fix(submissions): improve link validation UX, banner display, and error toasts (#547)

- Reconcile frontend link types with backend enum (github, demo, video, document, presentation, other)
- Allow up to 5 "other" links per submission with smart type-picking on Add Link and duplicate guards on type change
- Add 500-character cap and live counter on the optional Introduction field
- Pass banner through initialData on submission edit so the saved banner displays
- Add banner field to ParticipantSubmission so the type compiles
- Set mock-fill participation type from myTeam to avoid INDIVIDUAL submissions while on a team
- Switch submission error toasts to title + description with 8s duration so backend messages are readable
- Update SubmissionLinksTab icon mapping for the new link types

* fix(submissions): correct logo cropping and remove duplicate category badge on submission card (#549)

- Logo overlay on banner uses object-contain so wordmark logos are not cropped
- Render the category badge once instead of twice on the explore submissions card

* feat(blog): add Boundless x Trustless Work hackathon post and fit cover images (#551)

- Add content/blog/boundless-launches-first-hackathon-campaign.mdx for the May 13 hackathon launch announcement.
- BlogCard and BlogPostDetails cover images use object-contain so the full banner is visible (previously object-cover cropped wider banners).
- Update SHARE icons on the blog details page from the old brand color #99FF2D to the current brand primary #2eedaa.

+---
+
+# Boundless Launches Its First Hackathon Campaign
+
+Boundless is officially launching its first-ever hackathon today, **May 13th, 2026**.
+
+In collaboration with **[Trustless Work](https://www.trustlesswork.com/)**, we are bringing together builders, creatives, developers, and thinkers for a multi-day hybrid event focused on brainstorming and building ideas that will revolutionize Web3 and DeFi.
+
+The Boundless x [Trustless Work](https://www.trustlesswork.com/) Hackathon is designed to encourage experimentation, collaboration, and real-world problem-solving. Participants will have the opportunity to ideate and build projects on the **Stellar** ecosystem.
+
+---
+
+## Why Boundless
+
+The next wave of the internet is being built in Web3.
+
+Every day, new ideas emerge across payments, coordination, finance, and digital ownership. But for many builders, the gap between ideation and execution still remains difficult to cross.
+
+At Boundless, our mission is to help bridge that gap.
+
+We believe the next generation of Web3 products should be built on systems that prioritize **transparency, verification, efficiency, and seamless global collaboration** from the start.
+
+The Boundless x [Trustless Work](https://www.trustlesswork.com/) Hackathon is designed to help developers explore what that future could look like in practice.
+
+---
+
+## Build Faster with the [Trustless Work](https://www.trustlesswork.com/) Starter Kit
+
+The focus of this hack is to encourage innovative thinking and unique real-world problem-solving techniques. That is why we are partnering with **[Trustless Work](https://www.trustlesswork.com/)**, so teams can focus on:
+
+- Product design
+- Workflow architecture
+- User experience
+- Integrations
+- Application-level innovation
+
+[Trustless Work](https://www.trustlesswork.com/) allows teams to implement escrow systems from start to finish in a very short time. This is also why we have limited use cases to products that require escrow as the core infrastructure.
+
+To help participants move quickly from ideation to implementation, developers will have access to the **[Trustless Work Builder Starter Kit](https://www.trustlesswork.com/)**.
+
+The hackathon will also include workshops, mentorship sessions, and technical support from the team at [Trustless Work](https://www.trustlesswork.com/) to help participants navigate implementation challenges and refine their projects.
+
+---
+
+## Event Details
+
+The hackathon is a **hybrid event** taking place from **May 13th to May 16th**. The first three days will be held virtually, while the final day will be a physical event.
+
+Here is the breakdown of what to expect each day:
+
+- **May 13:** Welcome Ceremony, Onboarding, and Team Selection
+- **May 14:** Build Day Two
+- **May 15:** Build Day Three
+- **May 16:** Project Demos, Judging, and Awards
+
+Activities throughout the hackathon will include:
+
+- Workshops
+- Office hours
+
+The physical event will include:
+
+- Project showcases
+- Technical presentations
+- Judging sessions
+- Winner announcements
+- Award presentations
+
+**Other Details**
+
+- **Venue:** Block Hive, Nsukka, Enugu State, Nigeria
+- **Registration Deadline:** May 15th
+
+---
+
+## Prize Pool
+
+The Boundless x [Trustless Work](https://www.trustlesswork.com/) Hackathon will reward outstanding technical execution, product thinking, and real-world usability across categories signifying our judging criteria.
+
+**Main Winners**
+
+- 1st Place: **$500**
+- 2nd Place: **$300**
+- 3rd Place: **$200**
+
+**Special Awards**
+
+- Best UI/UX Design: **$100**
+- Best Real-World Use Case: **$100**
+- Best Technical Implementation: **$100**
+- Most Innovative Idea: **$100**
+- Best Use of [Trustless Work](https://www.trustlesswork.com/): **$100**
+
+---
+
+## Who Can Participate?
+
+The hackathon is open to **developers, designers, product builders**, and anyone interested in building internet-native coordination systems.
+
+Participants may hack alone or form teams of **2 to 5 members** across the participant scope. Participants do not need to arrive with a fully developed idea.
+
+---
+
+## What Should You Build?
+
+Participants are expected to build a focused product using [Trustless Work](https://www.trustlesswork.com/) primitives. The goal is not to build another generic escrow platform, but to create specific applications that solve real problems.
+
+Some possible directions include:
+
+- Freelance and milestone-based work platforms
+- Marketplace and e-commerce escrow systems
+- Grant distribution and bounty management tools
+- Crowdfunding and pre-order infrastructure
+- Rental agreements and security deposit flows
+- P2P stablecoin exchange applications
+- Trade finance coordination tools
+- AI agent payment and workflow systems
+
+Participants will also have flexible integration options depending on their preferred workflow. Teams can move quickly with low-code tooling, build with prebuilt components, or work directly with **SDKs and APIs** for more advanced customization and deeper product control.
