YoussefandClaude Opus 4.7 9aa09f1d60 Rebalance theme palette — Linen → cool slate · Studio → cool grey
Seven of Hallmark's 16 themes had warm-cream paper (Specimen, Atelier,
Newsprint, Salon, Linen, Studio, Riso). Switching themes felt
monochromatic — too many cards from the same hue band. Two converted:

## Linen — warm linen-yellow → cool slate

- paper:  oklch(89% 0.022 95) → oklch(91% 0.012 220)   (cool, slightly cooler L)
- accent: oklch(46% 0.06 95)  → oklch(40% 0.12 232)    (steel-blue, more chroma)
- ink: tinted toward the cool side at hue 215-220
- Display still IBM Plex Sans (geometric-sans is Linen's identity)
- Same fabric voice, different dye. Sits at the calm cool-paper end.

## Studio — warm cream-yellow → cool grey

- paper:  oklch(96.5% 0.014 95) → oklch(96.5% 0.005 200)  (cool grey, very subtle)
- ink: tinted toward hue 205 (cool)
- Forest-green accent KEPT (oklch 46% 0.140 145) — Studio's identity.
  The pairing of cool-grey paper + green accent reads as a research
  studio rather than a warm-bohemian-studio.
- Italic Fraunces display KEPT — typographic identity unchanged.
- Card shadow hue updated from warm 100 to cool 205.

## Result

Theme palette now spread across:
- Warm: Specimen, Atelier, Newsprint, Salon, Riso
- Cool: Linen, Studio, Garden, Almanac, Pastel, Sport
- Neutral: Brutal, Quiet
- Dark: Midnight, Terminal, Manifesto

No single hue band dominates the cycle.
