The right solution that I should have found first. Standard NeoForge + JEI tag, no mod or KubeJS hack needed.

Source-confirmed:

JEI defines Tags.HIDDEN_FROM_RECIPE_VIEWERS = c:hidden_from_recipe_viewers
IngredientVisibility.isIngredientVisible() consults this tag on every visibility check
NeoForge defines the same tag
REI and EMI follow the convention

Datapack file at data/c/tags/item/hidden_from_recipe_viewers.json adds both items. One file, zero mods.

pack: v0.31.2 — proper item hiding via c:hidden_from_recipe_viewers tag 2710dce479

Stop hacking around the problem -- use the standard cross-recipe-
viewer hide convention that both NeoForge and JEI define.

Source-level confirmation:

  mezz/JustEnoughItems @ 1.21.1
    CommonApi/.../api/constants/Tags.java
      HIDDEN_FROM_RECIPE_VIEWERS = c:hidden_from_recipe_viewers

    Library/.../ingredients/IngredientVisibility.java
      isIngredientVisible() calls
      ingredientHelper.isHiddenFromRecipeViewersByTags(typedIngredient)
      -> any item carrying this tag is hidden from JEI.

  neoforged/NeoForge @ 1.21.x
    common/Tags.java
      Tags.Items.HIDDEN_FROM_RECIPE_VIEWERS = c:hidden_from_recipe_viewers
      -> same tag, NeoForge agrees with JEI.

  EMI / REI also respect this tag (common convention).

So the proper modpack-shippable fix is a single datapack file:

  pack/overrides/world/datapacks/bns-fuel/data/c/tags/item/
    hidden_from_recipe_viewers.json
  {
    "replace": false,
    "values": [
      "alexsmobs:shattered_dimensional_carver",
      "alexsmobs:transmutation_table"
    ]
  }

No mod, no KubeJS, no CraftTweaker, no Item Obliterator JEI integration
(which doesn't exist for 1.21.1 NeoForge anyway). Just the tag the
recipe-viewer ecosystem agreed on years ago.

Item Obliterator + Necronomicon stay in the pack for what they actually
deliver on 1.21.1: inventory-pickup block + villager-trade removal +
right-click cancellation. The Capsid recipe override stays too as the
creation block.

The full disable stack now:
  - Tag (this commit)         -> Hidden from JEI / REI / EMI
  - Datapack capsid recipe    -> Can't be created in-world
  - Item Obliterator          -> Can't be picked up / right-clicked
                                 if obtained via /give or creative
