Phase 9 begins: bigger, sparser veins, a mine-through respawn block, left-out lines

Phase 8 approved (2026-11-09). Adrian's Phase 9 answers: left-out Pokemon rare
in fitting zones; legendaries from crafted summons; no public release.

- Ore veins more sporadic but bigger: nodes about 40 % rarer, veins about 30 %
  further apart, each one block larger in radius. 1.5-3x the ore overall; a
  new island is needed to see it. World check on the regenerated island passes.
- The respawn block (Regenerating Ore Veins' regenerator): the aim passes
  through it unless sneaking (mixin, the pack's first), so ore behind it can be
  mined; much fainter glass through KubeJS assets. Self-test
  regenerator_lets_the_aim_through casts a real ray.
- 31 lines (67 species) with no matching island biome, or no spawn data
  (Rotom), get rare homes in fitting zones (world/zones.json -> homeless).
  Existing spawns and guardians don't change. JEI data and quests regenerated.
- surface_nodes_lie_in_the_ground checks the node's centre column: a wider
  node's edge can lie under a tree or a slope.
- Roadmap: every implemented Pokemon obtainable; Iris and Complementary
  Reimagined as the default shader.

Self-tests and the island check pass.

 - **Balance pass** on levels, drop rates, vein timers, job cooldowns, hazard damage and machine output, all from `docs/balance.md`.
 - **Every implemented Pokémon is obtainable** (Adrian, 2026-11-09). Every species Cobblemon has a model for must be reachable somewhere in the world, even if rarely or through crafting: a wild spawn, evolving a wild line, a fossil, or a crafted or summoned encounter. Legendaries and the like count too; they can be very rare or expensive. Checked on 2026-11-09: 95 of 905 implemented species are not reachable by a wild spawn or by evolving a wild line (legendaries, fossils, and lines the zone assignment left out, such as Aron, Litwick and Piplup). Report what is missing with a tool or self-test so new Cobblemon versions can't reopen the gap.
+- **A shader pack by default** (Adrian, 2026-11-09). Ship [Iris](https://modrinth.com/mod/iris) (client only) and [Complementary Reimagined](https://modrinth.com/shader/complementary-reimagined), switched on for new players; players can turn it off or pick a lower profile. Iris 1.8.14-beta.1+1.21.1-neoforge (MR `KduFYu4t`) is built against Sodium 0.8.13, which the pack already pins; it is the only NeoForge 1.21.1 build for Sodium 0.8, and a beta. Complementary r5.9.3 (MR `Bqen1mJX`) has the most downloads of the common shader packs and keeps a vanilla-like look, which suits Cobblemon's models. Its license allows modpacks if it is credited where the pack is described, left unmodified, and added through Modrinth or CurseForge's own systems, never as an uploaded file: the private pack has to download it from Modrinth. Check that Cobblemon's models, the machine and boss particles and the see-through blocks render properly with it on, and measure the frame-rate cost.
 - **Performance.** Profile with spark on a server with realistic pen and machine counts; cap entity density through pasture config if needed.
 - **Multiplayer test** with Adrian's group.
 - **Release.** Final `docs/licenses.md`, credits and non-affiliation disclaimer; publish client and server packs on Modrinth and CurseForge as dependency-based packs.
