Preheat the oven to 350ºF and adjust rack to middle position.
Butter a 9-inch tart pan. Place almond flour, coconut flour, sugar, gelatin, arrowroot and sea salt in the bowl of a food processor. Pulse 2-3 times to combine. Add butter or coconut oil and pulse 10 times to combine and then process until mixture forms a dough. Press dough on bottom and up sides of tart pan. Place tart pan on top of a baking sheet. Bake for 12 minutes, or until just turning golden brown. As soon as the crust comes out of the oven, sprinkle the chocolate over top. Let the chocolate sit for 3 minutes and then using an offset spatula, spread melted chocolate evenly over crust. Cool for 15 minutes, then place tart in the refrigerator.
Pour the coconut milk into a medium saucepan and bring to a simmer. Meanwhile, place the yolks and sugar in the bowl of a standing mixture. Using a whisk attachment, whisk mixture on medium-high for 3 minutes until very thick. Reduce speed to low and add arrowroot. Whisk until incorporated. With mixer on low, slowly (very slowly) add the hot coconut milk to the egg mixture. When all of the coconut milk has been added, pour the coconut milk/egg mixture into the saucepan and heat over low heat. Whisk constantly until mixture forms a thick pudding. Remove from the heat and stir in the vanilla, butter, and almond extract. Pour pastry cream into a large bowl. Place a piece of parchment paper directly on the pastry cream (this will prevent it from forming a skin). Chill for about 45 minutes.
Pour the cooled pastry cream over the chocolate in the tart pan and spread evenly. Chill for about 3 hours. Place strawberries cut-side down on top of pastry cream, drizzle with melted chocolate. Serve.
