-Allow multiple encounters per route when shiny clause or dupes clause is active. Shiny clause lets a player catch a shiny regardless of first-encounter rule. Dupes clause lets them re-roll if the first encounter is a species already caught. Requires frontend logic to add additional encounters to a route and backend validation.

+Implement active enforcement for Dupes Clause and Shiny Clause in the encounter flow.
+
+## Dupes Clause
+
+When enabled, Pokemon from an already-caught evolution chain are **greyed out** in the encounter modal. This prevents catching duplicates within the same evolutionary family.
+
+- If you catch a Rattata, both Rattata and Raticate become unavailable
+- If you catch an Eevee (or any Eeveelution), the entire Eevee family is blocked
+- "Already caught" includes both alive and dead Pokemon from the current run
+- Greyed-out Pokemon should still be visible in the encounter list but clearly marked as ineligible (reduced opacity, strikethrough, or similar)
+- This requires knowing the full evolution chain for each Pokemon — use the existing evolution data to build family groups
+
+### Implementation notes
+- Build a lookup from pokemon_id → set of all pokemon in the same evolution family (walk the evolution tree in both directions)
+- On the encounter modal, cross-reference available route Pokemon against caught families
+- Grey out / mark as "duped" any Pokemon whose family already has a catch in the current run
+- Backend validation is optional (frontend-only is fine since this is a self-enforced rule)
+
+## Shiny Clause
+
+When enabled, shiny Pokemon may be caught regardless of the first-encounter-only rule. Rather than allowing multiple regular encounters per route, add a **dedicated Shiny Box** container.
+
+- Add a "Shiny Box" section on the run page (separate from the team/graveyard)
+- Shiny catches are not tied to a route — they're bonus catches stored in the shiny container
+- Shiny Box entries need: pokemon, nickname, catch level, and the route where found
+- Shinies in the box do NOT count against the one-encounter-per-route rule
+- The shiny box should be visually distinct (sparkle icon, gold/yellow accent)
+
+### Implementation notes
+- Add an `is_shiny` boolean field to the Encounter model (or a separate shiny encounters table)
+- Shiny encounters bypass the route-lock check on the backend
+- Frontend: add a "Log Shiny" button or a shiny toggle in the encounter modal
+- Display shiny box as a collapsible section similar to the graveyard
+
+## Checklist
+- [ ] Build evolution family lookup (pokemon_id → family set)
+- [ ] Grey out duped Pokemon in encounter modal when dupes clause is active
+- [ ] Add `is_shiny` field to encounter model + migration
+- [ ] Backend: allow shiny encounters to bypass route lock
+- [ ] Frontend: shiny toggle/button in encounter flow
+- [ ] Frontend: shiny box section on run page
+- [ ] Test with evolution chains (Eevee family, branching evolutions)
