New 'Capacity planning' tab (last one, after 'Chip roofline & B*').
Everything below is a dataframe table where a bullet list could have
gone, matching the user's 'mostly try to make tables to describe the
information' preference:
1. **Three-axis GPU sizing formula** (table: A/B/C rows with Formula,
Meaning, 'Grows with' columns)
2. **Live sizing calculator** (KPI cards + 3 number inputs — this is
the only interactive block on the tab)
3. **SLO standards by workload** (table: TTFT / TPOT targets for
voice/code/chat/agentic/batch, with 'what binds' column)
4. **Hybrid deployment layers** (table: Layer 1 elastic pool /
Layer 2 length-tier routing / Layer 3 disaggregated prefill/decode
with Serves / Key mechanism / Admission rule / Typical config)
5. **Binding-axis playbook** (table: for each of A/B/C — Symptom,
First lever, Second lever, Cost impact)
Removed the sizing calculator + 3 expanders from the bottom of the
Chip Roofline tab. Roofline tab is back to pure chip-vs-model /
formulas territory; planning tab has the workload / SLO / deployment
material.
Calculator uses the base sidebar chip (_default_machine) rather than
the roofline tab's knob-scaled chip, so results are stable across
navigation.
